a5c1c795a2 have the mc lowering process handle a few tail call forms, lowering them to 
jumps where possible and turning the TAILCALL marker in the instruction
asm string into a proper comment.

This eliminates a FIXME and is on the path to finishing:
rdar://7639610 - eliminate encoding and asm info for TAILJMPd TAILJMPr TAILJMPn, etc.

However, I can't eliminate the encodings for these instructions because the JIT
still exists and has its own copy of the encoder, sigh.

6a5db9c9c9 Implement the major chunk of PR7195: support for 'callw' 
in the integrated assembler.  Still some discussion to be
done.

77240e2337 MC: Simplify MayNeedRelaxation to not provide the fixups, so we can query it 
before encoding.

6a5cb8c84a Split out the x86_32 an x86_64 ELF backends as they handle ELF 
differently. This will make adding ELF support easier in the long run.

e5a79692cf MC/Mach-O/x86_64: Add a new hook for checking whether a particular section can 
be diced into atoms, and adjust getAtom() to take this into account.
 - This fixes relocations to symbols in fixed size literal sections, for
   example.

33433c1e3c MC/X86: Error out if we see a non-constant FK_Data_1 or FK_Data_2 fixup, since 
we don't currently support relaxing them.

c687bf7cb4 MC: Add TargetAsmBackend::createObjectWriter. 
- MCAssembler is now object-file independent, although we will surely need more work to fully support ELF/COFF.

3444d755d2 MCAssembler: Move ApplyFixup to the TargetAsmBackend, this is a target specific not object writer specific task.

26cbc4b1a3 MC/Darwin: Add a new target hook for whether the target uses "reliable" symbol differences, basically whether the assembler should attempt to understand atoms when using scattered symbols. 
Also, avoid some virtual call overhead.
