0076ca0da9 - When expanding a bit_convert whose src operand is also to be expanded and 
its expansion result type is equal to the result type of the bit_convert,
e.g. (i64 bit_convert (f64 op)) if FP is not legal
returns the result of the expanded source operand.
- Store f32 / f64 may be expanded to a single store i32/i64.

6ba11fbd75 Revert Nate's patch to fix X86/store-fp-constant.ll. With the dag combiner 
and legalizer separated like they currently are, I don't see a way to handle
this xform.

b7524b6d0e make this code more aggressive about turning store fpimm into store int imm. 
This is not sufficient to fix X86/store-fp-constant.ll

b3b285185f It seems the llvm::OStream class does not handle stream manipulators. 
For now, just grab the stream and perform the output on it directly.

e8da58b3f9 Properly mangles symbol table names 
Supports constant pools
Supports relocations to jump tables
Supports relocations within the data segment (global = address of global)
Allocates memory in a non-hacky for all non-code objects.

bb4e6d4d12 Proper fix for PR1037: to determine is a VR is a modref, check 1) whether it is 
tied to another oeprand, 2) whether is is being tied to by another operand. So
the destination operand of a two-address MI can be correctly identified.
