These instructions were changed to not embed the addressing mode within the MC instructions
We also need to update the corresponding assert stmt. Also add two test cases.

Fix the bad logic and add some sanity checking to detect bad instruction encoding;
and add a test case.

VFP Load/Store Multiple Instructions used to embed the IA/DB addressing mode within the
MC instruction; that has been changed so that now, for example, VSTMDDB_UPD and VSTMDIA_UPD
are two instructions. Update the ARMDisassemblerCore.cpp's DisassembleVFPLdStMulFrm()
to reflect the change.
Also add a test case.

The relevant instruction table entries were changed sometime ago to no longer take
<Rt2> as an operand. Modify ARMDisassemblerCore.cpp to accomodate the change and
add a test case.

o A8.6.195 STR (register) -- Encoding T1
o A8.6.193 STR (immediate, Thumb) -- Encoding T1
It has been changed so that now they use different addressing modes
and thus different MC representation (Operand Infos). Modify the
disassembler to reflect the change, and add relevant tests.

1. The ARM Darwin *r9 call instructions were pseudo-ized recently.
Modify the ARMDisassemblerCore.cpp file to accomodate the change.
2. The disassembler was unnecessarily adding 8 to the sign-extended imm24:
imm32 = SignExtend(imm24:'00', 32); // A8.6.23 BL, BLX (immediate)
// Encoding A1
It has no business doing such. Removed the offending logic.
Add test cases to arm-tests.txt.

Optimize trivial branches in CodeGenPrepare, which often get created from the
lowering of objectsize intrinsics. Unfortunately, a number of tests were relying
on llc not optimizing trivial branches, so I had to add an option to allow them
to continue to test what they originally tested.
This fixes <rdar://problem/8785296> and <rdar://problem/9112893>.

The insufficient encoding information of the combined instruction confuses the decoder wrt
UQADD16. Add extra logic to recover from that.
Fixed an assert reported by Sean Callanan

for calls to weak symbols with a definition has the appearance of working
with LLVM-generated code because weak symbol definitions are put in their
own sections.

Introduce a variable in the AsmParserExtension whether [] is valid in an

enabled by default.
Joerg, if you would like to resubmit with the behavior conditionalized to be
X86-ELF only, that's fine.
