Reid Spencer f37dc65b08 Bail on the getInferredCast idea. Remove the function and convert 
remaining uses to more specific casts.

Chris Lattner c20b7e878a If we have ScalarSSE, we can select bitconvert into single instructions. 
This compiles bitcast.ll:test3/test4 into:

_test3:
        movd %xmm0, %eax
        ret
_test4:
        movd %edi, %xmm0
        ret

Chris Lattner 55c17f9177 Fix PR1033 and CodeGen/X86/bitcast.ll, by expanding bitcast to a load/store pair. 
This could be better, readme entry pending.

Reid Spencer a16f930aac Can't make these fail now with just BitCast. Previous failures must have 
been in conjunction with something else. By right, they should just be
BitCasts.

Evan Cheng 62cdc3f011 - Fix X86-64 JIT by temporarily disabling code that treats GV address as 32-bit 
immediate in small code model. The JIT cannot ensure GV's are placed in the
lower 4G.
- Some preliminary support for large code model.

Chris Lattner c209b584eb add an instcombine xform. This speeds up 462.libquantum from 9.78s to 
7.48s.  This regression is due to unforseen consequences of the cast patch.

Reid Spencer c4dacf2455 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.
