Justin Bogner c475e1bc77 llvm-cov: Fix handling of line zero appearing in a line table
Reading line tables in llvm-cov was pretty broken, but would happen to
work as long as no line in the table was 0. It's not clear to me
whether a line of zero *should* show up in these tables, but deciding
to read a string in the middle of the line table is certainly the
wrong thing to do if it does.

I've also added some comments, as trying to figure out what this block
of code was doing was fairly unpleasant.

Daniel Sanders 6ef0a2f1be [tablegen] !strconcat accepts more than two arguments but this wasn't documented or tested.
Summary:
* Updated the documentation
* Added a test for >2 arguments
* Added a check for the lexical concatenation
* Made the existing test a bit stricter.

Nico Weber 4b2acde21a Teach GlobalDCE how to remove empty global_ctor entries.
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.

Tom Stellard eba61071d7 R600/SI: Only create one instruction when spilling/restoring register v3
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.

Tim Northover 523b5a43fb ARM64: refactor NEON post-indexed loads & stores (MC).
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.
