want to hoist instructions out of the loop and above the header.

7efba85d41 Fix r141744.
1. The speculation check may not have been performed if the BB hasn't had a load
   LICM candidate.
2. If the candidate would be CSE'ed, then go ahead and speculatively LICM the
   instruction even if it's in high register pressure situation.

1c062c24ab Fix -widen-vmovs liveness issues.
When widening a copy, we are reading a larger register that may not be
live.  Use an <undef> flag to tell the register scavenger and machine
code verifier that we know the value isn't defined.

We now widen:

  %S6<def> = COPY %S4<kill>, %D3<imp-def>

into:

  %D3<def> = VMOVD %D2<undef>, pred:14, pred:%noreg, %S4<imp-use,kill>

This also keeps the <kill> flag on %S4 so we don't inadvertently kill a
live value in %S5.

Finally, ensure that ARMBaseInstrInfo::setExecutionDomain() preserves
the <undef> flag when converting VMOVD to VORR.

6618a241f7 Add a new wrapper node for a DILexicalBlock that encapsulates it and a
file. Since it should only be used when necessary propagate it through
the backend code generation and tweak testcases accordingly.

This helps with code like in clang's test/CodeGen/debug-info-line.c where
we have multiple #line directives within a single lexical block and want
to generate only a single block that contains each file change.

c83693f5b0 N.B. This is with the new EH scheme:
The blocks with invokes have branches to the dispatch block, because that more
correctly models the behavior of the CFG. The dispatch of course has edges to
the landing pads. Those landing pads could contain invokes, which then have
branches back to the dispatch. This creates a loop. The machine LICM pass looks
at this loop and thinks it can hoist elements out of it. But because the
dispatch is an alternate entry point into the program, the hoisted instructions
won't be executed.

I wasn't able to get a testcase which was small and could reproduce all of the
time. The function_try_block.cpp in llvm-test was where this showed up.
