7ea6816a05 [StatepointLowering] Minor nfc refactoring
Now that StatepointLoweringInfo represents base pointers, derived
pointers and gc relocates as SmallVectors and not ArrayRefs, we no
longer need to allocate "backing storage" on stack in LowerStatepoint.
So elide the backing storage, and inline the trivial body of
getIncomingStatepointGCValues.

5cf6af4222 MC: Don't access the filesystem in MCContext's constructor
MCContext shouldn't be accessing the filesystem - that's a gross
layering violation and makes it awkward to use as a library or in a
daemon where it may not even be allowed filesystem access.

The CWD lookup here is normally redundant anyway, since the calling
context either also looks up the CWD or sets this to something more
specific. Here, we fix up the one caller that doesn't already set up a
debug compilation dir and make it clear that the responsibility for
such set up is in the users of MCContext.

981c18bd80 Drop comdats from the dst module if they are not selected.
A really unfortunate design of llvm-link and related libraries is that
they operate one module at a time.

This means they can copy a GV to the destination module that should not
be there in the final result because a later bitcode file takes
precedence.

We already handled cases like a strong GV replacing a weak for example.

One case that is not currently handled is a comdat replacing another.
This doesn't happen in ELF, but with COFF largest selection kind it is
possible.

In "llvm-link a.ll b.ll" if the selected comdat was from a.ll,
everything will work and we will not copy the comdat from b.ll.

But if we run "llvm-link b.ll a.ll", we fail to delete the already
copied comdat from b.ll. This patch fixes that.

e2dab65fbb CodeGen: check return types match when emitting tail call to builtin.
We were just completely ignoring the types when determining whether we could
safely emit a libcall as a tail call. This is clearly wrong.

Theoretically, we could dig deeper looking for incidental matches (much like
the generic code in Analysis.cpp does), but it's probably not worth it for the
few libcalls that exist.

609a56f4f8 [LoopVersioning] Relax an assert for LCSSA PHIs
When you have multiple LCSSA (single-operand) PHIs that are converted
into two-operand PHIs due to versioning, only assert that the PHI
currently being converted has a single operand.  I.e. we don't want to
check PHIs that were converted earlier in the loop.

Fixes PR27023.

83dbb9a4a4 [X86][SSE] Reapplied: Simplify vector LOAD + EXTEND on pre-SSE41 hardware
Improve vector extension of vectors on hardware without dedicated VSEXT/VZEXT instructions.

We already convert these to SIGN_EXTEND_VECTOR_INREG/ZERO_EXTEND_VECTOR_INREG but can further improve this by using the legalizer instead of prematurely splitting into legal vectors in the combine as this only properly helps for lowering to VSEXT/VZEXT.

Removes a lot of unnecessary any_extend + mask pattern - (Fix for PR25718).

Reapplied with a fix for PR26953 (missing vector widening legalization).

490efbdf4e [PATCH] Force LoopReroll to reset the loop trip count value after reroll.
It's a bug fix. 
For rerolled loops SE trip count remains unchanged. It leads to incorrect work of the next passes.
My patch just resets SE info for rerolled loop forcing SE to re-evaluate it next time it requested.
I also added a verifier call in the exisitng test to be sure no invalid SE data remain. Without my fix this test would fail with -verify-scev.

09f0b0071f Add "first class" lowering for deopt operand bundles
Summary:
After this change, deopt operand bundles can be lowered directly by
SelectionDAG into STATEPOINT instructions (which are then lowered to a
call or sequence of nop, with an associated __llvm_stackmaps entry0.
This obviates the need to round-trip deoptimization state through
gc.statepoint via RewriteStatepointsForGC.

59fe6640ec [MemorySSA] Consider def-only BBs for live-in calculations.
If we have a BB with only MemoryDefs, live-in calculations will ignore
it. This means we get results like this:

define void @foo(i8* %p) {
  ; 1 = MemoryDef(liveOnEntry)

  br i1 undef, label %if.then, label %if.end

  br label %if.end

if.end:
