cabbae653e Tweak to the fix in r156212, as with the change in removing the shift the 
SignExtend32<22>(Val<<1) also needs to change to SignExtend32<21>(Val) .

914223010c Fix issues with the ARM bl and blx thumb instructions and the J1 and J2 bits 
for the assembler and disassembler.  Which were not being set/read correctly
for offsets greater than 22 bits in some cases.

c988e0c521 ARM refactor away a bunch of VLD/VST pseudo instructions. 
With the new composite physical registers to represent arbitrary pairs
of DPR registers, we don't need the pseudo-registers anymore. Get rid of
a bunch of them that use DPR register pairs and just use the real
instructions directly instead.

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

8d24618975 ARM NEON VST2 assembly parsing and encoding. 
Work in progress. Parsing for non-writeback, single spaced register lists
works now. The rest have the representations better factored, but still
need more to be able to parse properly.

d146a02c79 ARM assembly parsing and encoding for VLD2 with writeback. 
Refactor the instructions into fixed writeback and register-stride
writeback variants to simplify the offset operand (no more optional
register operand using reg0). This is a simpler representation and allows
the assembly parser to more easily handle these instructions.

Add tests for the instruction variants now supported.
