84c287e33c Move TableGen's parser and entry point into a library
This is the first step towards splitting LLVM and Clang's tblgen executables.

526adabe87 Don't allow 32-bit only instructions to be disassembled in 64-bit mode. Fixes part of PR10700.

a948cb9058 Fix disassembling of PAUSE instruction. Fixes PR10900. Also fixed NOP disassembling to ignore OpSize and REX.W.

94ce535647 Make IC_VEX* not inherit from IC_*. Prevents instructions with no VEX form from disassembling to their non-VEX form. Also prevents weak filter collisons that were keeping valid VEX instructions from decoding properly. Make VEX_L* not inherit from VEX_* because the VEX.L bit always important. This stops packed int VEX encodings from being disassembled when specified with VEX.L=1. Fixes PR10831 and PR10806.

c3fd523731 X86 table-generator and disassembler support for the AVX
instruction set.  This code adds support for the VEX prefix
and for the YMM registers accessible on AVX-enabled
architectures.  Instruction table support that enables AVX
instructions for the disassembler is in an upcoming patch.

04cc307edd Table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit
incarnations), integrated into the MC framework.  

The disassembler is table-driven, using a custom TableGen backend to 
generate hierarchical tables optimized for fast decode.  The disassembler 
consumes MemoryObjects and produces arrays of MCInsts, adhering to the 
abstract base class MCDisassembler (llvm/MC/MCDisassembler.h).

The disassembler is documented in detail in

- lib/Target/X86/Disassembler/X86Disassembler.cpp (disassembler runtime)
- utils/TableGen/DisassemblerEmitter.cpp (table emitter)

You can test the disassembler by running llvm-mc -disassemble for i386
or x86_64 targets.  Please let me know if you encounter any problems
with it.
