76b29b518d 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.

16b7dd64e9 Fix a bug in the x86 disassembler's symbolic disassembly support for Jcc-Jump
if Condition Is Met instuctions that was not correctly determining the target
instruction.

So for a jne rel32 instruction:

% cat x.s
.byte 0x0f, 0x85, 0x09, 0x00, 0x00, 0x00
% as x.s

it was incorrectly deterining the target:

% otool -q -tv a.out 
a.out:
(__TEXT,__text) section
0000000000000000	jne	0xd

and with the fix it gets this correct as:

% otool -q -tv a.out
a.out:
(__TEXT,__text) section
0000000000000000	jne	0xf

b80d571ea8 Updated the llvm-mc disassembler C API to support for the X86 target.
rdar://10873652

As part of this I updated the llvm-mc disassembler C API to always call the
SymbolLookUp call back even if there is no getOpInfo call back.  If there is a
getOpInfo call back that is tried first and then if that gets no information
then the  SymbolLookUp is called.  I also made the code more robust by
memset(3)'ing to zero the LLVMOpInfo1 struct before then setting
SymbolicOp.Value before for the call to getOpInfo.  And also don't use any
values from the  LLVMOpInfo1 struct if getOpInfo returns 0.  And also don't
use any of the ReferenceType or ReferenceName values from SymbolLookUp if it
returns NULL. rdar://10873563 and rdar://10873683

For the X86 target also fixed bugs so the annotations get printed. 

Also fixed a few places in the ARM target that was not producing symbolic
operands for some instructions.  rdar://10878166
