Chandler Carruth ed0881b2a6 Use the new script to sort the includes of every file under lib.
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

Craig Topper 963305b450 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.

Craig Topper b8aec08819 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.

Kevin Enderby 216ac31971 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

Kevin Enderby 6fbcd8d439 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
