Various x86 disassembler fixes.
...
Add VEX_LIG to scalar FMA4 instructions.
Use VEX_LIG in some of the inheriting checks in disassembler table generator.
Make use of VEX_L_W, VEX_L_W_XS, VEX_L_W_XD contexts.
Don't let VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE inherit from their non-L forms unless VEX_LIG is set.
Let VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE inherit from all of their non-L or non-W cases.
Increase ranking on VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE so they get chosen over non-L/non-W forms.

Update the X86 disassembler to use xacquire and xrelease when appropriate.
...
This is a bit tricky as the xacquire and xrelease hints use the same bytes,
0xf2 and 0xf3, as the repne and rep prefixes.
Fortunately llvm has different llvm MCInst Opcode enums for rep/xrelease
and repne/xacquire. So to make this work a boolean was added the
InternalInstruction struct as part of the Prefix state which is set with the
added logic in readPrefixes() when decoding an instruction to determine
if these prefix bytes are to be disassembled as xacquire or xrelease. Then
we let the matcher pick the normal prefix instructionID and we change the
Opcode after that when it is set into the MCInst being created.

Updated the llvm-mc disassembler C API to support for the X86 target.
...
rdar://10873652
As part of this I updated the llvm-mc disassembler C API to always call the
SymbolLookUp call back even if there is no getOpInfo call back. If there is a
getOpInfo call back that is tried first and then if that gets no information
then the SymbolLookUp is called. I also made the code more robust by
memset(3)'ing to zero the LLVMOpInfo1 struct before then setting
SymbolicOp.Value before for the call to getOpInfo. And also don't use any
values from the LLVMOpInfo1 struct if getOpInfo returns 0. And also don't
use any of the ReferenceType or ReferenceName values from SymbolLookUp if it
returns NULL. rdar://10873563 and rdar://10873683
For the X86 target also fixed bugs so the annotations get printed.
Also fixed a few places in the ARM target that was not producing symbolic
operands for some instructions. rdar://10878166
