642b329104 Expand some more vector operations not supported by Neon.

74dc72e89b Expand all v2f64 arithmetic operations for Neon. 
Radar 7200803.  (This should also fix the
SingleSource/UnitTests/Vector/sumarray-dbl test.)

e4863f4759 Handle AddrMode4 for Thumb2 in rewriteT2FrameIndex. This occurs for 
VLDM/VSTM instructions, and without this check, the code assumes that an
offset is allowed, as it would be with VLDR/VSTR.  The asm printer,
however, silently drops the offset, producing incorrect code.  Since the
address register in this case is either the stack or frame pointer, the
spill location ends up conflicting with some other stack slot or with
outgoing arguments on the stack.

ca9c42c4da Added the first bits of the ARM target assembler to llvm-mc. For now it only 
parses the .word directive as 4 bytes and ARMAsmParser::ParseInstruction will
give an error is called.  Broke out the test of the .word directive into two
different test cases, one for x86 and one for arm.

c5ea263a23 remove DebugLoc from MCInst and eliminate "Comment printing" from 
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

634cca377a hoist the call to processDebugLoc out of the generated 
asm printer into the "printInstruction" routine.  This
fixes a problem where the experimental asmprinter would
drop debug labels in some cases, and fixes issues on ppc/xcore
where pseudo instructions like "mr" didn't get debug locs properly.

It is annoying that this moves the call from one place into each
target, but a future set of more invasive refactorings will fix
that problem.

3fb2b1ede3 Clean up LSDA name generation and use for SJLJ exception handling. This 
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
and making it a GV available for reference would be even better, but is
beyond the scope of what I'm looking to solve at this point.

Objective C++ code could generate function names that broke the previous
scheme. This fixes that.
