9765c6ecde X86: Fix encoding of 'movd %xmm0, %rax' 
The assembly string for the VMOVPQIto64rr instruction incorrectly lacked the 'v'
prefix, resulting in mis-assembly of the vanilla movd instruction.

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

d8b7aa2613 Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang does. Enhance 
the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

25f6dfd108 Revert part of r141274. Only need to change encoding for xchg %eax, %eax in 64-bit mode. This is because in 64-bit mode xchg %eax, %eax implies zeroing the upper 32-bits of RAX which makes it not a NOP. In 32-bit mode using NOP encoding is fine.

c37d4bbf1f Fix llvm-mc handing of x86 instructions that take 8-bit unsigned immediates. 
llvm-mc gives an "invalid operand" error for instructions that take an unsigned
immediate which have the high bit set such as:
    pblendw $0xc5, %xmm2, %xmm1
llvm-mc treats all x86 immediates as signed values and range checks them.
A small number of x86 instructions use the imm8 field as a set of bits.
This change only changes those instructions and where the high bit is not
ignored.  The others remain unchanged.
