Sean Callanan 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.

Michael J. Spencer ab425d8360 I swear I did a make clean and make before committing all this...

Chris Lattner d8adec70f3 factor the operand list (and related fields/operations) out of 
CodeGenInstruction into its own helper class.  No functionality change.

Bruno Cardoso Lopes c2f87b7bb2 Reapply r105521, this time appending "LLU" to 64 bit 
immediates to avoid breaking the build.

Chris Lattner fdd2614330 revert r105521, which is breaking the buildbots with stuff like this:

Bruno Cardoso Lopes 594fa26317 Initial AVX support for some instructions. No patterns matched 
yet, only assembly encoding support.

Sean Callanan 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.
