Chandler Carruth 91d19d8e93 Sort the #include lines for utils/... 
I've tried to find main moudle headers where possible, but the TableGen
stuff may warrant someone else looking at it.

Craig Topper 3f23c1a8b9 Remove code for setting the VEX L-bit as a function of operand size from the code emitters and the disassembler table builder. Fix a couple instructions that were still missing VEX_L.

Dmitri Gribenko 2bc1d483fe Fix Doxygen issues: 
* wrap code blocks in \code ... \endcode;
* refer to parameter names in paragraphs correctly (\arg is not what most
  people want -- it starts a new paragraph).

Craig Topper 25ea4e5ad3 Add X86 BEXTR instruction. This instruction uses VEX.vvvv to encode Operand 3 instead of Operand 2 so needs special casing in the disassembler and code emitter. Ultimately, should pass this information from tablegen

Craig Topper f18c896337 Add support in the disassembler for ignoring the L-bit on certain VEX instructions. Mark instructions that have this behavior. Fixes PR10676.

Eli Friedman 0318036c4d Make the disassembler able to disassemble a bunch of instructions with names in the TableGen files containing "64" on x86-32. This includes a bunch of x87 instructions, like fld, and a bunch of SSSE3 instructions on MMX registers like pshufb. Part of PR8873.

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.

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:

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.
