Dan Gohman 40503396da Eliminate more uses of llvm-as and llvm-dis.

Evan Cheng ad6f3ff2c0 For Darwin / x86_64, override -relocation-model=static to pic if the output is assembly since Darwin assembler does not really support -static codeine.
I view this as a temporary workaround until the assembler / linker changes.

Dan Gohman fc262babc3 Revert r72734. The Darwin assembler doesn't support the static
relocation model on x86-64. Higher level logic should override
the relocation model to PIC on x86_64-apple-darwin.

Evan Cheng 448641d87c On Darwin x86_64 small code model doesn't guarantee code address fits in 32-bit.

Dan Gohman 2fe6bee5b6 Teach DAGCombine to fold constant offsets into GlobalAddress nodes,
and add a TargetLowering hook for it to use to determine when this
is legal (i.e. not in PIC mode, etc.)

This allows instruction selection to emit folded constant offsets
in more cases, such as the included testcase, eliminating the need
for explicit arithmetic instructions.

This eliminates the need for the C++ code in X86ISelDAGToDAG.cpp
that attempted to achieve the same effect, but wasn't as effective.

Also, fix handling of offsets in GlobalAddressSDNodes in several
places, including changing GlobalAddressSDNode's offset from
int to int64_t.

The Mips, Alpha, Sparc, and CellSPU targets appear to be
unaware of GlobalAddress offsets currently, so set the hook to
false on those targets.
