bc71c2fd8e Reapply r237453 with a fix for the test timeouts.
The test timeouts were due to instcombine fighting itself. Regression test added.
Original log message:

Canonicalize min/max expressions correctly.

This patch introduces a canonical form for min/max idioms where one operand
is extended or truncated. This often happens when the other operand is a
constant. For example:

  %1 = icmp slt i32 %a, i32 0
    %2 = sext i32 %a to i64
      %3 = select i1 %1, i64 %2, i64 0

Would now be canonicalized into:

  %1 = icmp slt i32 %a, i32 0
    %2 = select i1 %1, i32 %a, i32 0
      %3 = sext i32 %2 to i64

This builds upon a patch posted by David Majenemer
(https://www.marc.info/?l=llvm-commits&m=143008038714141&w=2). That pass
passively stopped instcombine from ruining canonical patterns. This
patch additionally actively makes instcombine canonicalize too.

Canonicalization of expressions involving a change in type from int->fp
or fp->int are not yet implemented.

f01f1c413a [x86] Distinguish the 'o', 'v', 'X', and 'i' inline assembly memory constraints.
Summary:
But still handle them the same way since I don't know how they differ on
this target.

Of these, 'o' and 'v' are not tested but were already implemented.

I'm not sure why 'i' is required for X86 since it's supposed to be an
immediate constraint rather than a memory constraint. A test asserts
without it so I've included it for now.

No functional change intended.

3ac70da982 MachineSink: Collect registers before clearing their killflags.
Currently whenever we sink any instruction, we do clearKillFlags for
every use of every use operand for that instruction, apparently there
are a lot of duplication, therefore compile time penalties.

This patch collect all the interested registers first, do clearKillFlags
for it all together at once at the end, so we only need to do
clearKillFlags once for one register, duplication is avoided.

8081057fca [MemCpyOpt] Turn memcpy from just-memset'd source into memset.
There's no point in copying around constants, so, when all else fails,
we can still transform memcpy of memset into two independent memsets.

To quote the example, we can turn:
  memset(dst1, c, dst1_size);
  memcpy(dst2, dst1, dst2_size);
into:
  memset(dst1, c, dst1_size);
  memset(dst2, c, dst2_size);
When dst2_size <= dst1_size.

Like r235232 for copy constructors, this can occur in move constructors.

24f0469865 [PPC64] Add vector pack/unpack support from ISA 2.07
This patch adds support for the following new instructions in the
Power ISA 2.07:

  vpksdss
  vpksdus
  vpkudus
  vpkudum
  vupkhsw
  vupklsw

These instructions are available through the vec_packs, vec_packsu,
vec_unpackh, and vec_unpackl built-in interfaces.  These are
lane-sensitive instructions, so the built-ins have different
implementations for big- and little-endian, and the instructions must
be marked as killing the vector swap optimization for now.

The first three instructions perform saturating pack operations.  The
fourth performs a modulo pack operation, which means it can be
represented with a vector shuffle, and conversely the appropriate
vector shuffles may cause this instruction to be generated.  The other
instructions are only generated via built-in support for now.

Appropriate tests have been added.

There is a companion patch to clang for the rest of this support.

c5f2ba0401 MC: Merge MCSymbol and MCSymbolData
Turn `MCSymbolData` into a field inside of `MCSymbol`.  Keep all the old
API alive for now, so that consumers can be updated in a later commit.
This means we still temporarily need the back pointer from
`MCSymbolData` to `MCSymbol`, but I'll remove it in a follow-up.

This optimizes for object emission over assembly emission.  By removing
the `DenseMap` in `MCAssembler`, llc memory usage drops from around 1040
MB to 1001 MB (3.8%).

(I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc`;
see r236629 for details.)

6c16124807 MC: Change MCAssembler::Symbols to a vector
Instead of an intrusive double-linked linked list, use a
`std::vector<>`.  This saves a pointer per symbol and simplifies
`MCSymbolData`.  Otherwise, no functionality change here.

While I measured a memory drop from around 1047MB to 1040MB (0.6%) --
and this is a decent cleanup in its own right -- it's primarily a
preparation patch for merging `MCSymbol` and `MCSymbolData`.  I'll post
an updated patch for that to the list in a moment.

Summary:
This is a pass for speculative execution of instructions for simple if-then (triangle) control flow. It's aimed at GPUs, but could perhaps be used in other contexts. Enabling this pass gives us a 1.0% geomean improvement on Google benchmark suites, with one benchmark improving 33%.

Credit goes to Jingyue Wu for writing an earlier version of this pass.

Patched by Bjarke Roune. 

Test Plan:
This patch adds a set of tests in test/Transforms/SpeculativeExecution/spec.ll
The pass is controlled by a flag which defaults to having the pass not run.

49f69b8e25 Canonicalize min/max expressions correctly.
This patch introduces a canonical form for min/max idioms where one operand

  %1 = icmp slt i32 %a, i32 0
  %2 = sext i32 %a to i64
  %3 = select i1 %1, i64 %2, i64 0

Would now be canonicalized into:

  %1 = icmp slt i32 %a, i32 0
  %2 = select i1 %1, i32 %a, i32 0
  %3 = sext i32 %2 to i64

This builds upon a patch posted by David Majenemer
(https://www.marc.info/?l=llvm-commits&m=143008038714141&w=2). That pass
passively stopped instcombine from ruining canonical patterns. This

eb9033d963 Allow min/max detection to see through casts.
This teaches the min/max idiom detector in ValueTracking to see through
casts such as SExt/ZExt/Trunc. SCEV can already do this, so we're bringing
non-SCEV analyses up to the same level.

The returned LHS/RHS will not match the type of the original SelectInst
any more, so a CastOp is returned too to inform the caller how to
convert to the SelectInst's type.

No in-tree users yet; this will be used by InstCombine in a followup.

39a7d6e91d [DependenceAnalysis] Fix for PR21585: collectUpperBound triggers asserts
collectUpperBound hits an assertion when the back edge count is wider then the desired type.

If that happens, truncate the backedge count.

Patch by Philip Pfaffe!

039eb5a7b8 [mips] [IAS] Fix expansion of negative 32-bit immediates for LI/DLI.
Summary:
To maintain compatibility with GAS, we need to stop treating negative 32-bit immediates as 64-bit values when expanding LI/DLI.
This currently happens because of sign extension.

To do this we need to choose the 32-bit value expansion for values which use their upper 33 bits only for sign extension (i.e. no 0's, only 1's).

4fa71b66a8 Add SDNodes for umin, umax, smin and smax.
This adds new SDNodes for signed/unsigned min/max. These nodes are built from
select/icmp pairs matched at SDAGBuilder stage.

This patch adds the nodes, as well as legalization support and sets them to
be "expand" for all targets.

NFC for now; this will be tested when I switch AArch64 to using these new
nodes.

fa93d0e1c6 [PlaceSafepoints] Fix a bug that came in with rL236672.
Transfer the calling convention from the invoke being replaced by
PlaceStatepoints to the new invoke to gc.statepoint created.  Add a test
case that would have caught this issue.

4c4b944e83 [PlaceSafepoints] Fix a bug that came in with rL236672.
rL236672 would generate all invoke statepoints with deopt args set to a
list containing the single element "0", instead of an empty list.

Also add a test case that would have caught this.

634e01a3e5 Stop resetting SanitizeAddress in TargetMachine::resetTargetOptions. NFC.
Instead of doing that, create a temporary copy of MCTargetOptions and reset its
SanitizeAddress field based on the function's attribute every time an InlineAsm
instruction is emitted in AsmPrinter::EmitInlineAsm. 

This is part of the work to remove TargetMachine::resetTargetOptions (the FIXME
added to TargetMachine.cpp in r236009 explains why this function has to be
removed).
