Changed register names (and pointer keywords) to be lower case when using Intel X86 assembler syntax.

Patch by Richard Mitton.

As these two instructions in AVX extension are privileged instructions for
special purpose, it's only expected to be used in inlined assembly.

This is used for all the expensive system instructions.

but it generates int3 on x86 instead of ud2.

Emacs-tag and some comment fix for all ARM, CellSPU, Hexagon, MBlaze, MSP430, PPC, PTX, Sparc, X86, XCore.

not depend on In32BitMode.  Use the sysexitq mnemonic for the version with the
REX.W prefix and only allow it only In64BitMode.  rdar://9738584

Add X86 INVPCID instruction. Add 32/64-bit predicates to INVEPT, INVVPID, VMREAD, and VMWRITE to remove hack from X86RecognizableInstr.

Fix register printing in disassembling of push/pop of segment registers and in/out in Intel syntax mode. Fixes PR10960

InstAlias doesn't allow matching immediate operands, so we have to write
C++ code to do this.

It doesn't look like anything is wrong with the checkin,
but the new test cases expose a mem bug in AsmParser.

sense, when the instruction takes the 16-bit ax register or m16 memory
location.  These changes to llvm-mc matches what the darwin assembler allows
for these instructions.  Also added the missing flex (without the wait prefix)
and ud2a as an alias to ud2 (still to add ud2b).

word forms and suffixed versions to match the darwin assembler in 32-bit and
64-bit modes.  This is again for use just with assembly source for llvm-mc .

some compiler pseudo instructions and Pat<> patterns
out to X86InstrCompiler.td
