This allows us to eliminate many temporary vectors, and theirassociated malloc/free pairs.

1. Make the arguments const like the other ConstantFold* functions.
2. Clean up evaluateFCmpRelation so it makes sense for floating point.
3. Implement the use of evaluateFCmpRelation to fold floating point CEs
4. Shorten a variable name so more things fit on one line.
5. Fix various comments.

This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

well as a vector of constant*'s. It turns out that this is more efficient
and all of the clients want to do that, so we should cater to them.

Move a bunch of (now) private stuff from ConstantFolding.h into
ConstantFolding.cpp.
This _finally_ gets us to a place where we have a sane constant folder. The
rules are:
1. LLVM clients now use ConstantExpr::get* methods to fold constants. If they
cannot be folded, a constantexpr is created, so these methods always return
valid Constant*'s.
2. The implementation of ConstantExpr::get* uses the functions exposed by
ConstantFolding.h to try to fold constants. If they cannot be folded,
they should return a null pointer.
3. The implementation of ConstantFolding can do whatever it wants, and only
has one client (Constants.cpp)
This cuts down on the wierd dependencies, and eliminates the two interfaces.
The old constanthandling interface was especially bad for clients to use
because almost none of them took the failure condition into consideration,
thus leading to obscure problems.

this whole refactoring: allow constant folding methods to return something
other than predefined classes, allow them to return generic Constant*'s.
