cd773b0d10 Dump the old va_arg and va_next upgrade support. No need to keep track of 
the current basic block any more either.

980b8e4169 Finally get the casting right in this file. Also, remove some unnecessary 
casting because sdiv doesn't require operand signs to match any more.

adeea85f7d - Switch X86-64 JIT to large code size model. 
- Re-enable some codegen niceties for X86-64 static relocation model codegen.
- Clean ups, etc.

6a9de21df5 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

28a5079f58 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.

2c35691a02 - 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.

4cb4234c17 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.
