869fe12cc0 MC/X86: Add a dummy implementation of MCFixup generation for hacky X86 MCCodeEmitter.

ce97b75c1d Disable unittests/ADT/BitVectorTest on PPC Darwin. 
It fails with a release build only, for reasons
as yet unknown.  (If there's a better way to Xfail
things here let me know, doesn't seem to be any
prior art in unittests.)

d32c02f314 Per PR 6219, factored AsmWriterInst and AsmWriterOperand 
out of the AsmWriterEmitter.  This patch does the physical
code movement, but leaves the implementation unchanged. I'll
make any changes necessary to generalize the code in a
separate patch.

9e8528fc5c fix X86 encoder to output [disp] only addresses with no SIB byte 
in X86-32 mode.  This is still required in x86-64 mode to avoid
forming [disp+rip] encoding.  Rewrite the SIB byte decision logic
to be actually understandable.

518bb53485 move target-independent opcodes out of TargetInstrInfo 
into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

4152778605 Radar 7417921 
tMOVCCi pattern only valid for low registers, as the Thumb1 mov immediate to
register instruction only works with low registers. Allowing high registers
for the instruction resulted in the assembler choosing the wide (32-bit)
encoding for the mov, but LLVM though the instruction was only 16 bits wide,
so offset calculations for constant pools became incorrect, leading to
out of range constant pool entries.

0b23dc0cc8 Fixed a bug in the PBQP allocator's findCoalesces method. 
Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with.

Move pass to right before SimplifyLibCalls - which is
moved down a bit so we can take advantage of a few opts.
