Eric Astor 4a7aa252a3 [X86][AsmParser] re-introduce 'offset' operator ...

Summary:
Amend MS offset operator implementation, to more closely fit with its MS counterpart:

    1. InlineAsm: evaluate non-local source entities to their (address) location
    2. Provide a mean with which one may acquire the address of an assembly label via MS syntax, rather than yielding a memory reference (i.e. "offset asm_label" and "$asm_label" should be synonymous
    3. address PR32530

Based on http://llvm.org/D37461

Fix broken test where the break appears unrelated.

- Set up appropriate memory-input rewrites for variable references.

- Intel-dialect assembly printing now correctly handles addresses by adding "offset".

- Pass offsets as immediate operands (using "r" constraint for offsets of locals).
