6d81a7d2ae Implement createIntegerCast and createFPCast factory methods for handling 
integer and floating point cast creation. createIntegerCast generates
ZExt/SExt, BitCast or Trunc. createFPCast generates FPExt, Bitcast, or
FPTrunc.

6b538cfc5c Provide a getOpcode() method on CmpInst to ensure the opcode is returned 
as the right type. Use this to shorten some code.

848414e49c Implement new cast creation functions for both instructions and constant 
expressions. These will get used to reduce clutter as we replace various
calls to createInferredCast and getCast.

56667123b7 Take a baby step towards getting rid of inferred casts. Provide methods on 
CastInst and ConstantExpr that allow the signedness to be explicitly passed
in and reliance on signedness removed from getCastOpcode. These are
temporary measures useful during the conversion of inferred casts.

3da59db637 For PR950: 
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.

45fb3f3cb2 For PR950: 
First in a series of patches to convert SetCondInst into ICmpInst and
FCmpInst using only two opcodes and having the instructions contain their
predicate value. Nothing uses these classes yet. More patches to follow.

3822ff5c71 For PR950:

AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not
dependent on the sign of their operands.

1628cec4d7 For PR950:

bytecode and assembler are bacwards compatible, however.
