977585f6e1 Filter out repeated sections from the X86 disassembler modRMTable. Saves about ~43K from a released build. Unfortunately the disassembler tables are still upwards of 800K.

a4bd7d9c3c Various x86 disassembler fixes. 
Add VEX_LIG to scalar FMA4 instructions.
Use VEX_LIG in some of the inheriting checks in disassembler table generator.
Make use of VEX_L_W, VEX_L_W_XS, VEX_L_W_XD contexts.
Don't let VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE inherit from their non-L forms unless VEX_LIG is set.
Let VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE inherit from all of their non-L or non-W cases.
Increase ranking on VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE so they get chosen over non-L/non-W forms.

stuff may warrant someone else looking at it.

e2e98bb26b Add a new compression type to ModRM table that detects when the memory modRM byte represent 8 instructions and the reg modRM byte represents up to 64 instructions. Reduces modRM table from 43k entreis to 25k entries. Based on a patch from Manman Ren.

3f200a7638 Add more indirection to the disassembler tables to reduce amount of space used to store the operand types and encodings. Store only the unique combinations in a separate table and store indices in the instruction table. Saves about 32K of static data.

f083691b6d 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.

99ad3cc23e Fix disassembler handling of CRC32 which is an odd instruction that uses 0xf2 as an opcode extension and allows the opsize prefix. This necessitated adding IC_XD_OPSIZE and IC_64BIT_XD_OPSIZE contexts. Unfortunately, this increases the size of the disassembler tables. Fixes PR10702.

316c7bfe37 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.

5a51ccdc0f 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.

18fa59f381 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.
