0e88464871 Fix ARM SjLj-EH dispatch setup code. <rdar://problem/10444602> 
The EmitBasePointerRecalculation function has 2 problems, one minor and one
fatal.  The minor problem is that it inserts the code at the setjmp
instead of in the dispatch block.  The fatal problem is that at the point
where this code runs, we don't know whether there will be a base pointer,
so the entire function is a no-op.  The base pointer recalculation needs to
be handled as it was before, by inserting a pseudo instruction that gets
expanded late.

Most of the support for the old approach is still here, but it no longer
has any connection to the eh_sjlj_dispatchsetup intrinsic.  Clean up the
parts related to the intrinsic and just generate the pseudo instruction
directly.

5ea426cfa8 Enable -widen-vmovs by default. 
This will widen 32-bit register vmov instructions to 64-bit when
possible.  The 64-bit vmovd instructions can then be translated to NEON
vorr instructions by the execution dependency fix pass.

The copies are only widened if they are marked as clobbering the whole
D-register.

044acb8bee ARM assembly parsing for register range syntax for VLD/VST register lists. 
For example,
vld1.f64 {d2-d5}, [r2,:128]!

Should be equivalent to:
vld1.f64 {d2,d3,d4,d5}, [r2,:128]!

It's not documented syntax in the ARM ARM, but it is consistent with what's
accepted for VLDM/VSTM and is unambiguous in meaning, so it's a good thing to
support.

2709f65821 Break false dependencies before partial register updates. 
Two new TargetInstrInfo hooks lets the target tell ExecutionDepsFix
about instructions with partial register updates causing false unwanted
dependencies.

The ExecutionDepsFix pass will break the false dependencies if the
updated register was written in the previoius N instructions.

The small loop added to sse-domains.ll runs twice as fast with
dependency-breaking instructions inserted.

4e05d7f12c Supporting inline memmove isn't going to be worthwhile. The only way to avoid

bc077320e1 ARM vldm and vstm VFP instructions can take a data type suffix. 
It's ignored by the assembler when present, but is legal syntax. Other
instructions have something similar, but for some mnemonics it's
only sometimes not significant, so this quick check in the parser will
need refactored into something more robust soon-ish. This gets some
basics working in the meantime.

bc4e9ca90e Mips MC object code emission improvements: 
"With this patch we can now generate runnable Mips code through LLVM
direct object emission. We have run numerous simple programs, both C
and C++ and with -O0 and -O3 from the output. The code is not production
ready, but quite useful for experimentation." Patch and message by
