[SDAG] Recursively legalize both vector mulo results
Split out from D61692 per RKSimon's suggestion. Vector op
legalization will automatically recursively legalize the returned

Otherwise it will end up getting legalized only during op
legalization, by which point it might be too late (though I'm not

There are codegen differences because expansion occurs earlier now
and we don't get a DAGCombiner run in between.

[ThinLTO] Auto-hide prevailing linkonce_odr only when all copies eligible
Summary:
We hit undefined references building with ThinLTO when one source file
contained explicit instantiations of a template method (weak_odr) but
there were also implicit instantiations in another file (linkonce_odr),
and the latter was the prevailing copy. In this case the symbol was
marked hidden when the prevailing linkonce_odr copy was promoted to
weak_odr. It led to unsats when the resulting shared library was linked
with other code that contained a reference (expecting to be resolved due
to the explicit instantiation).
Add a CanAutoHide flag to the GV summary to allow the thin link to
identify when all copies are eligible for auto-hiding (because they were
all originally linkonce_odr global unnamed addr), and only do the
auto-hide in that case.
Most of the changes here are due to plumbing the new flag through the
bitcode and llvm assembly, and resulting test changes. I augmented the
existing auto-hide test to check for this situation.

DebugInfo: Only move types out of type units if they're named or type united
Follow up to r359122, after a bug was reported in it - the original
change too aggressively tried to move related types out of type units,

be declared-but-not-defined.
A step beyond that is that some types in type units can be anonymous, if
they are types with a name for linkage purposes (eg: "typedef struct { }
x;"). So ensure those don't get turned into plain declarations (without
signatures) because, lacking names, they can't be resolved to the
definition.

Compile time tweak for libcall lookup
If we have a large module which is mostly intrinsics, we hammer the lib call lookup path from CodeGenPrepare. Adding a fastpath reduces compile by 15% for one such example.
The problem is really more general than intrinsics - a module with lots of non-intrinsics non-libcall calls has the same problem - but we might as well avoid an easy case quickly.

Region end markers must specify the region name. The only exception is for when

Incorrect region end markers are no longer ignored. Instead, the tool reports an

Larger-scale testing goes in PhaseOrdering or the test-suite.
I've hopefully preserved the intent by taking what was completely

means that sub-register indices currently are (and will continue to be)

AMDGPU: Select VOP3 form of add
The VOP3 form should always be the preferred selection, to be shrunk
later. This should only be an optimization issue, but this partially
works around a problem from clobbering VCC when SIFixSGPRCopies
rewrites an SCC defining operation directly to VCC.
3 of the testcases are regressions from failing to fold the immediate
in cases it should. These can be avoided by improving the VCC liveness
handling in SIFoldOperands. Simply increasing the threshold to
computeRegisterLiveness works, although this is common enough that VCC
liveness should probably be tracked throughout the pass. The hack of
leaving behind an implicit_def instruction to avoid breaking iterator
wastes instruction count, which inhibits finding the VCC def in long
chains of adds. Doing this however exposes different, worse looking
regressions from poor scheduling behavior. This could probably be
avoided around by forcing the shrink of the addc here, but the
scheduler should probably be fixed.
The r600 add test needs to be split out because it asserts on the
arguments in the new test during the calling convention lowering.

[FileCheck] Fix code style of method comments
Summary:
Fix various issues in code style of method comments:
1) Move all heading comments to all non-static methods near their
declaration in the FileCheck.h header file.
2) Harmonize the action verb in doxygen comments for methods to always
be in third person
3) Use \returns instead of free text "return" and "returns".
4) Document a couple more parameters while at it.

[InstCombine] When turning sext into zext due to known bits, return the new ZExt instead of calling replaceinstuseswith
The worklist loop that we're returning back to should be able to do the repacement itself. This is how we normally do replacements.
My main motivation was that I observed that we weren't preserving the name of the result when we do this transform. The replacement code in the worklist loop will call takeName as part of the replacement.

InsertBinop tries to move insertion-points out of loops for expressions

When assigning the definitions of an instruction we were updating
the available registers while walking the definitions. Some of
those definitions may be from physical registers and thus, they are
not available for other definitions to take, but by the time we see
that we may have already assign these registers to another
virtual register.
Fix that by walking through all the definitions and mark as unavailable
the physical register definitions, then do the virtual register assignments.
