This moves most of GlobalOpt's constructor optimization
code out of GlobalOpt into Transforms/Utils/CDtorUtils.{h,cpp}. The
public interface is a single function OptimizeGlobalCtorsList() that
takes a predicate returning which constructors to remove.

GlobalOpt calls this with a function that statically evaluates all
constructors, just like it did before. This part of the change is
behavior-preserving.

Also add a call to this from GlobalDCE with a filter that removes global
constructors that contain a "ret" instruction and nothing else – this
fixes PR19590.

.file records are supposed to have a section identifier of 65534
(IMAGE_SCN_DEBUG) rather than 0.  This is spelt out clearly within the PE/COFF
specification.  Fix this minor oversight with the implementation for support for
.file records.

The register spiller assumes that only one new instruction is created
when spilling and restoring registers, so we need to emit pseudo
instructions for vector register spills and lower them after
register allocation.

v2:
  - Fix calculation of lane index
  - Extend VGPR liveness to end of program.

v3:
  - Use SIMM16 field of S_NOP to specify multiple NOPs.

Previously, LLVM had no knowledge that these instructions actually
modified their address register: fine if they never end up in CodeGen,
but when I'd rather like to write some patterns for them it becomes a
disaster.

The change is mostly straightforward, I think the most significant
design decision was to *always* put the address write-back first. This
allows loads and stores to be accessed more uniformly, for example
permitting the continued sharing of the InstAlias definitions.

I also discovered that the custom Decode logic is no longer needed, so
I removed it.

No tests, because there should be no functionality change.

Export definitions in a module definition file is as follows:

Previously we did not support =internalname, so users couldn't export
symbols from a DLL with a different name.

The Preprocessor::Initialize() function already offers a clear interface to
