Remove llvm-ld and llvm-stub (which is only used by llvm-ld).

llvm-ld is no longer useful and causes confusion and so it is being removed.

* Does not work very well on Windows because it must call a gcc like driver to
  assemble and link.
* Has lots of hard coded paths which are wrong on many systems.
* Does not understand most of ld's options.
* Can be partially replaced by llvm-link | opt | {llc | as, llc -filetype=obj} |
  ld, or fully replaced by Clang.

I know of no production use of llvm-ld, and hacking use should be
replaced by Clang's driver.

-=head1 NAME
-
-llvm-ld - LLVM linker
-
-=head1 SYNOPSIS
-
-B<llvm-ld> <options> <files>
-
-=head1 DESCRIPTION
-
-The B<llvm-ld> tool takes a set of LLVM bitcode files and links them
-together into a single LLVM bitcode file.  The output bitcode file can be
-another bitcode file or an executable bitcode program.  Using additional
-options, B<llvm-ld> is able to produce native code executables.
-
-The B<llvm-ld> tool is the main linker for LLVM. It is used to link together
-the output of LLVM front-end compilers and run "link time" optimizations (mostly
-the inter-procedural kind).
-
-The B<llvm-ld> tools attempts to mimic the interface provided by the default
-system linker so that it can act as a I<drop-in> replacement.
-
-=head2 Search Order
-
-When looking for objects specified on the command line, B<llvm-ld> will search 
-for the object first in the current directory and then in the directory 
-specified by the B<LLVM_LIB_SEARCH_PATH> environment variable.  If it cannot 
-find the object, it fails.
-
-When looking for a library specified with the B<-l> option, B<llvm-ld> first
-attempts to load a file with that name from the current directory.  If that
-fails, it looks for libI<library>.bc, libI<library>.a, or libI<library>.I<shared
-library extension>, in that order, in each directory added to the library search
-path with the B<-L> option.  These directories are searched in the order they
-are specified.  If the library cannot be located, then B<llvm-ld> looks in the
-directory specified by the B<LLVM_LIB_SEARCH_PATH> environment variable.  If it
-does not find a library there, it fails.
-
-The I<shared library extension> may be I<.so>, I<.dyld>, I<.dll>, or something
-different, depending upon the system.
-
-The B<-L> option is global.  It does not matter where it is specified in the
-list of command line arguments; the directory is simply added to the search path
-and is applied to all libraries, preceding or succeeding, in the command line.
-
-=head2 Link order
-
-All object and bitcode files are linked first in the order they were 
-specified on the command line.  All library files are linked next.  
-Some libraries may not be linked into the object program; see below.
-
-=head2 Library Linkage
-
-Object files and static bitcode objects are always linked into the output
-file.  Library archives (.a files) load only the objects within the archive
-that define symbols needed by the output file.  Hence, libraries should be
-listed after the object files and libraries which need them; otherwise, the
-library may not be linked in, and the dependent library will not have its
-undefined symbols defined.
-
-=head2 Native code generation
-
-The B<llvm-ld> program has limited support for native code generation, when
-using the B<-native> or B<-native-cbe> options. Native code generation is
-performed by converting the linked bitcode into native assembly (.s) or C code
-and running the system compiler (typically gcc) on the result.
-
-=head1 OPTIONS
-
-=head2 General Options
-
-=over 
-
-=item B<-help>
-
-Print a summary of command line options.
-
-=item B<-v>
-
-Specifies verbose mode. In this mode the linker will print additional
-information about the actions it takes, programs it executes, etc. 
-
-=item B<-stats>
-
-Print statistics.
-
-=item B<-time-passes>
-
-Record the amount of time needed for each pass and print it to standard
-error.
-
-=back 
-
-=head2 Input/Output Options
-
-=over
-
-=item B<-o> F<filename>
-
-This overrides the default output file and specifies the name of the file that
-should be generated by the linker. By default, B<llvm-ld> generates a file named
-F<a.out> for compatibility with B<ld>. The output will be written to
-F<filename>.
-
-=item B<-b> F<filename>
-
-This option can be used to override the output bitcode file name. By default, 
-the name of the bitcode output file is one more ".bc" suffix added to the name 
-specified by B<-o filename> option.
-
-=item B<-l>F<name>
-
-This option specifies the F<name> of a library to search when resolving symbols
-for the program. Only the base name should be specified as F<name>, without a
-F<lib> prefix or any suffix. 
-
-=item B<-L>F<Path>
-
-This option tells B<llvm-ld> to look in F<Path> to find any library subsequently
-specified with the B<-l> option. The paths will be searched in the order in
-which they are specified on the command line. If the library is still not found,
-a small set of system specific directories will also be searched. Note that
-libraries specified with the B<-l> option that occur I<before> any B<-L> options
-will not search the paths given by the B<-L> options following it.
-
-=item B<-link-as-library>
-
-Link the bitcode files together as a library, not an executable. In this mode,
-undefined symbols will be permitted.
-
-=item B<-r>
-
-An alias for -link-as-library.
-
-=item B<-native>
-
-Generate a native machine code executable.
-
-When generating native executables, B<llvm-ld> first checks for a bitcode
-version of the library and links it in, if necessary.  If the library is
-missing, B<llvm-ld> skips it.  Then, B<llvm-ld> links in the same
-libraries as native code.
-
-In this way, B<llvm-ld> should be able to link in optimized bitcode
-subsets of common libraries and then link in any part of the library that
-hasn't been converted to bitcode.
-
-=item B<-native-cbe>
-
-Generate a native machine code executable with the LLVM C backend.
-      
-This option is identical to the B<-native> option, but uses the
-C backend to generate code for the program instead of an LLVM native
-code generator.
-
-=back
-
-=head2 Optimization Options
-
-=over 
-
-=item B<-disable-inlining>
-
-Do not run the inlining pass. Functions will not be inlined into other
-functions.
-
-=item B<-disable-opt>
-
-Completely disable optimization.
-
-=item B<-disable-internalize>
-
-Do not mark all symbols as internal.
-
-=item B<-verify-each>
-
-Run the verification pass after each of the passes to verify intermediate
-results.
-
-=item B<-strip-all>
-
-Strip all debug and symbol information from the executable to make it smaller.
-
-=item B<-strip-debug>
-
-Strip all debug information from the executable to make it smaller.
-
-=item B<-s>
-
-An alias for B<-strip-all>.
-
-=item B<-S>
-
-An alias for B<-strip-debug>.
-
-=item B<-export-dynamic>
-
-An alias for B<-disable-internalize>
-
-=item B<-post-link-opt>F<Path>
-
-Run post-link optimization program. After linking is completed a bitcode file
-will be generated. It will be passed to the program specified by F<Path> as the
-first argument. The second argument to the program will be the name of a
-temporary file into which the program should place its optimized output. For
-example, the "no-op optimization" would be a simple shell script:
-
-    #!/bin/bash
-    cp $1 $2
-
-=back
-
-=head1 EXIT STATUS
-
-If B<llvm-ld> succeeds, it will exit with 0 return code.  If an error occurs,
-it will exit with a non-zero return code.
-
-=head1 ENVIRONMENT
-
-The C<LLVM_LIB_SEARCH_PATH> environment variable is used to find bitcode
-libraries. Any paths specified in this variable will be searched after the C<-L>
-options.

-<p>The configure script is getting things wrong because the LLVM linker allows

-

-<p>Yes, you can use LLVM to convert code from any language LLVM supports to C.
-   Note that the generated C code will be very low level (all loops are lowered
-   to gotos, etc) and not very pretty (comments are stripped, original source
-   formatting is totally lost, variables are renamed, expressions are
-   regrouped), so this may not be what you're looking for. Also, there are
-   several limitations noted below.<p>
-
-<p>Use commands like this:</p>
-
-<ol>
-  <li><p>Compile your program with llvm-g++:</p>
-
-<pre class="doc_code">
-% llvm-g++ -emit-llvm x.cpp -o program.bc -c
-</pre>
-
-      <p>or:</p>
-
-<pre class="doc_code">
-% llvm-g++ a.cpp -c -emit-llvm
-% llvm-g++ b.cpp -c -emit-llvm
-% llvm-ld a.o b.o -o program
-</pre>
-
-   <p>This will generate program and program.bc.  The .bc
-      file is the LLVM version of the program all linked together.</p></li>
-
-  <li><p>Convert the LLVM code to C code, using the LLC tool with the C
-      backend:</p>
-
-<pre class="doc_code">
-% llc -march=c program.bc -o program.c
-</pre></li>
-
-  <li><p>Finally, compile the C file:</p>
-
-<pre class="doc_code">
-% cc x.c -lstdc++
-</pre></li>
-
-</ol>
-
-<p>Using LLVM does not eliminate the need for C++ library support.  If you use
-   the llvm-g++ front-end, the generated code will depend on g++'s C++ support
-   libraries in the same way that code generated from g++ would.  If you use
-   another C++ front-end, the generated code will depend on whatever library
-   that front-end would normally require.</p>
-
-<p>If you are working on a platform that does not provide any C++ libraries, you
-   may be able to manually compile libstdc++ to LLVM bitcode, statically link it
-   into your program, then use the commands above to convert the whole result
-   into C code.  Alternatively, you might compile the libraries and your
-   application into two different chunks of C code and link them.</p>
-
-<p>Note that, by default, the C back end does not support exception handling.
-   If you want/need it for a certain program, you can enable it by passing
-   "-enable-correct-eh-support" to the llc program.  The resultant code will use
-   setjmp/longjmp to implement exception support that is relatively slow, and
-   not C++-ABI-conforming on most platforms, but otherwise correct.</p>
-
-<p>Also, there are a number of other limitations of the C backend that cause it
-   to produce code that does not fully conform to the C++ ABI on most
-   platforms. Some of the C++ programs in LLVM's test suite are known to fail
-   when compiled with the C back end because of ABI incompatibilities with
-   standard C++ libraries.</p>

-//
-// Note that if someone (or a script) deletes the executable program generated,

-/*===- llvm-stub.c - Stub executable to run llvm bitcode files ------------===//

-//                     The LLVM Compiler Infrastructure

-// This file is distributed under the University of Illinois Open Source
-// License. See LICENSE.TXT for details.

-//===----------------------------------------------------------------------===//
-//
-// This tool is used by the gccld program to enable transparent execution of
-// bitcode files by the user.  Specifically, gccld outputs two files when asked
-// to compile a <program> file:
-//    1. It outputs the LLVM bitcode file to <program>.bc
-//    2. It outputs a stub executable that runs lli on <program>.bc
-//
-// This allows the end user to just say ./<program> and have the JIT executed
-// automatically.  On unix, the stub executable emitted is actually a bourne
-// shell script that does the forwarding.  Windows does not like #!/bin/sh
-// programs in .exe files, so we make it an actual program, defined here.
