a3d4e67e43 [SimplifyCFG] Further improve our ability to remove redundant catchpads
In r256814, we managed to remove catchpads which were trivially redudant
because they were the same SSA value.  We can do better using the same
algorithm but with a smarter datastructure by hashing the SSA values
within the catchpad and comparing them structurally.

3bab5f489e [RS4GC] Simplify handling of Constants in findBaseDefiningValue(). NFC.
Summary:
Previously there were three conditionals, checking for global
variables, undef values and everything constant except these two, all three
returning the same value.  This commit replaces them by one conditional.

Summary:
This commit renames GCRelocateOperands to GCRelocateInst and makes it an
intrinsic wrapper, similar to e.g. MemCpyInst.  Also, all users of
GCRelocateOperands were changed to use the new intrinsic wrapper instead.

d28c1bc303 [WinEH] Simplify unreachable catchpads
Summary:
At least for CoreCLR, a catchpad which immediately executes an
`unreachable` instruction indicates that the exception can never have a
matching type, and so such catchpads can be removed, and so can their
catchswitches if the catchswitch becomes empty.

7f4aa70ca5 Revert "[X86] Use push-pop for materializing small constants under 'minsize'"
The red zone consists of 128 bytes beyond the stack pointer so that the
allocation of objects in leaf functions doesn't require decrementing
rsp.  In r255656, we introduced an optimization that would cheaply
materialize certain constants via push/pop.  Push decrements the stack
pointer and stores it's result at what is now the top of the stack.
However, this means that using push/pop would encroach on the red zone.
PR26023 gives an example where this corrupts an object in the red zone.

46850ab55f AMDGPU/SI: Consolidate FLAT patterns
Summary:
We had to sets of identical FLAT patterns one inside the
HasFlatAddressSpace predicate and one inside the useFlatForGloabl
predicate.  This patch merges these sets into a single pattern
under the isCIVI predicate.

The reason we can remove the predicates is that when MUBUF instructions
are legal, the instruction selector will prefer selecting those over
FLAT instructions because MUBUF patterns have a higher complexity score.
So, in this case having patterns for FLAT instructions will have no effect.

This change also simplifies the process for forcing global address space
loads to use FLAT instructions, since we no only have to disable the
MUBUF patterns instead of having to disable the MUBUF patterns and
enable the FLAT patterns.

1aeaf6cd63 [MDA] Don't be quite as conservative for noalias functions
If we encounter a noalias call that alias analysis can't analyse, we can fall down into the generic call handling rather than giving up entirely. I noticed this while reading through the code for another purpose.

I can't seem to write a test case which changes; that sorta makes sense given any test case would have to be an inconsistency in AA. Suggestions welcome.

96b46d19c0 MachineInstrBundle: Fix reversed isSuperRegisterEq() call
Unfortunately this fix had the effect of exposing the
-verify-machineinstrs FIXME of X86InstrInfo.cpp in two testcases for
which I disabled it for now.
Two testcases also have additional pushq/popq where the corrected code
cannot prove that %rax is dead any longer. Looking at the examples, this
could potentially be fixed by improving computeRegisterLiveness() to check
the live-in lists of the successors blocks when reaching the end of a
block.

This fixes http://llvm.org/PR25951.

fac1bfe37d AMDGPU: add +xnack feature
Summary:
Enabling this feature will account for the two SGPRs used by the hardware
to store the XNACK_MASK physically.

The hardware only requires this reservation when the XNACK feature is
explicitly enabled. At some point, HSA will probably want to do that, but
it does increase SGPR register pressure, so leave it disabled by default
for now (but do add a small test).

0ecf67f2fe Clarify that the bypassSlowDivision optimization operates on a single BB [v2]
Update some comments to be more explicit.

Change bypassSlowDivision and the functions it calls so that they take
BasicBlock*s and Instruction*s, rather than Function::iterator&s and
BasicBlock::iterator&s.

Change the APIs so that the caller is responsible for updating the
iterator, rather than the callee. This makes control flow much easier

e14c161b0e [MemoryBuiltins] Remove isOperatorNewLike by consolidating non-null inference handling
This patch removes the isOperatorNewLike predicate since it was only being used to establish a non-null return value and we have attributes specifically for that purpose with generic handling. To keep approximate the same behaviour for existing frontends, I added the various operator new like (i.e. instances of operator new) to InferFunctionAttrs. It's not really clear to me why this isn't handled in Clang, but I didn't want to break existing code and any subtle assumptions it might have.

Once this patch is in, I'm going to start separating the isAllocLike family of predicates. These appear to be being used for a mixture of things which should be more clearly separated and documented. Today, they're being used to indicate (at least) aliasing facts, CSE-ability, and default values from an allocation site.

7f410b17a7 [WinEH] Update CoreCLR EH state numbering
Summary:
Fix the CLR state numbering to generate correct tables, and update the lit
test to verify them.

The CLR numbering assigns one state number to each catchpad and
cleanuppad.

It also computes two tree-like relations over states:
 1) Each state has a "HandlerParentState", which is the state of the next
    outer handler enclosing this state's handler (same as nearest ancestor
    per the ParentPad linkage on EH pads, but skipping over catchswitches).
 2) Each state has a "TryParentState", which:
    a) for a catchpad that's not the last handler on its catchswitch, is
       the state of the next catchpad on that catchswitch.
    b) for all other pads, is the state of the pad whose try region is the
       next outer try region enclosing this state's try region.  The "try
       regions are not present as such in the IR, but will be inferred
       based on the placement of invokes and pads which reach each other
       by exceptional exits.

Catchswitches do not get their own states, but each gets mapped to the
state of its first catchpad.

Table generation requires each state's "unwind dest" state to have a lower
state number than the given state.

Since HandlerParentState can be computed as a function of a pad's
ParentPad, and TryParentState can be computed as a function of its unwind
dest and the TryParentStates of its children, the CLR state numbering
algorithm first computes HandlerParentState in a top-down pass, then
computes TryParentState in a bottom-up pass.

Also reword some comments/names in the CLR EH table generation to make the
distinction between the different kinds of "parent" clear.

98732e397c AMDGPU: Avoid assertions after SGPR spilling failed
Summary:
The comment explains it: emitError does not necessarily exit the compilation
process, and then using NoRegister leads to assertions later on.
This generates incorrect code, of course, but the user should know to not use
the result when an error has been emitted.

It would be nice to have a test-case for this inside the LLVM repository,
but llc exits on error. shader-db tests trigger the underlying issue at least
on Tonga.

ab99ec2ce7 Fix a horrible infloop in value tracking in the face of dead code.
Amazingly, we just never triggered this without:
1) Moving code around for MetadataTracking so that a certain *different*
   amount of inlining occurs in the per-TU compile step.
2) Then you LTO opt or clang with a bootstrap, and get inlining, loop
   opts, and GVN line up everything *just* right.

I don't really know how we didn't hit this before. We really need to be
fuzz testing stuff, it shouldn't be hard to trigger. I'm working on
crafting a reduced nice test case, and will submit that when I have it,
but I want to get LTO build bots going again.

f124911f7a [X86] Make hasFP constant time
We need a frame pointer if there is a push/pop sequence after the
prologue in order to unwind the stack.  Scanning the instructions to
figure out if this happened made hasFP not constant-time which is a
violation of expectations.  Let's compute this up-front and reuse that
computation when we need it.

82e76d50b1 [LICM] Make instruction sinking funclet-aware
We had two bugs here:
- We might try to sink into a catchswitch, causing verifier failures.
- We will succeed in sinking into a cleanuppad but we didn't update the
  funclet operand bundle.

This fixes PR26000.

ae62636ef8 [TableGen] Fix a bug that caused the wrong name for a record built from a multiclass containing a defm called NAME that references another multiclass that contains a defm that uses NAME concatenated with other strings.
It would end up doing the concatenations from the second multiclass twice. This occured because SetValue detected a self assignment when trying to set the value of NAME to a VarInit called NAME. NAME is special here and it will get cleaned up later. So add a flag to suppress the self assignment check for this case.

Strangely the self-assignment error was returning false indicating it wasn't an error, but it wasn't doing the right thing. So this also changes it to report an error.

This fixes the names of some AVX512 FMA instructions that showed this double expansion.
