3ca6382120 X86: Better diagnostics for 32-bit vs. 64-bit mode mismatches.
When an instruction as written requires 32-bit mode and we're assembling
in 64-bit mode, or vice-versa, issue a more specific diagnostic about
what's wrong.

be02a90de1 Add support of RTM from TSX extension
- Add RTM code generation support throught 3 X86 intrinsics:
  xbegin()/xend() to start/end a transaction region, and xabort() to abort a
  tranaction region

2fbc239e4f [ms-inline asm] Add support for the [] operator. Essentially, [expr1][expr2] is
equivalent to [expr1 + expr2].  See test cases for more examples.

1386e9b7b1 Add intrinsics, code gen, assembler and disassembler support for the SSE4a extrq and insertq instructions.
This required light surgery on the assembler and disassembler
because the instructions use an uncommon encoding. They are
the only two instructions in x86 that use register operands
and two immediates.

b80d571ea8 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
