508a1f4db1 Check to make sure we can select the instruction before trying to put the
operands into a register.  Otherwise, we may materialize dead code.

b95fc31aa2 Sink codegen optimization level into MCCodeGenInfo along side relocation model
and code model. This eliminates the need to pass OptLevel flag all over the
place and makes it possible for any codegen pass to use this information.

eaab6ef6eb 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.

3805d85e38 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.

e43862b6a6 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.

c2ecf3efbf 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.
