Renamed as.cpp => llvm-as.cpp; this should've happened a long time ago.

-// LLVM 'AS' UTILITY
-//
-// This utility may be invoked in the following manner:
-// llvm-as --help - Output information about command line switches
-// llvm-as [options] - Read LLVM asm from stdin, write bytecode to stdout
-// llvm-as [options] x.ll - Read LLVM asm from the x.ll file, write bytecode
-// to the x.bc file.
-//
