Instead of

we now generate

 cmp w0, #1

06d3099445 Reapply: "Remove debug location from common tail when tail-merging"
This reapplies revision 285093.  Original commit message:

The branch folding pass tail merges blocks into a common-tail.  However, the
tail retains the debug information from one of the original inputs to the
merge (chosen randomly).  This is a problem for sampled-based PGO, as hits
on the common-tail will be attributed to whichever block was chosen,
irrespective of which path was actually taken to the common-tail.

This patch fixes the issue by nulling the debug location for the common-tail.

9bbf2376bc Fix nondeterministic output in local stack slot alloc pass
This finds all of the references to a frame index in a function, and
sorts by the offset. If multiple instructions use the same offset,
nothing was breaking the tie for sorting.

This avoids the test failures the reverted r282999 introduced.

ca2ff9d43b [IndVarSimplify][DebugLoc] When widening the exit loop condition, correctly reuse the debug location of the original comparison.
When the loop exit condition is canonicalized as a != compaison, reuse the
debug location of the original (non canonical) comparison.

Before this patch, the debug location of the new icmp was obtained from the
loop latch terminator. This patch fixes the issue by correctly setting the
IRBuilder's "current debug location" to the location of the original compare.

6232f507e5 [AVX-512] Add scalar vfmsub/vfnmsub mask3 intrinsics
Summary: Clang's intrinsic header currently tries to negate the third operand of a vfmadd mask3 in order to create vfmsub, but this fails isel. This patch adds scalar vfmsub and vfnmsub mask3 that we can use instead to avoid the negate. This is consistent with the packed instructions.

140a0d7e69 [XRay] Implement llvm-xray extract, start of the llvm-xray tool
Usage:

  llvm-xray extract <object file> [-o <filename or '-'>]

The tool gets the XRay instrumentation map from an object file and turns
it into YAML.  We first support ELF64 sleds on x86_64 binaries, with
provision for supporting other supported platforms and formats later.

This is the first of a many-part change to fully implement the
`llvm-xray` tool.

We also define a subcommand registration and dispatch mechanism to be
used by other further subcommand implementations for llvm-xray.

38133c4e94 [Sparc] Don't overlap variable-sized allocas with other stack variables.
On SparcV8, it was previously the case that a variable-sized alloca
might overlap by 4-bytes the last fixed stack variable, effectively
because 92 (the number of bytes reserved for the register spill area) !=
96 (the offset added to SP for where to start a DYNAMIC_STACKALLOC).

It's not as simple as changing 96 to 92, because variables that should
be 8-byte aligned would then be misaligned.

For now, simply increase the allocation size by 8 bytes for each dynamic
allocation -- wastes space, but at least doesn't overlap. As the large
comment says, doing this more efficiently will require larger changes in
llvm.

Also adds some test cases showing that we continue to not support
dynamic stack allocation and over-alignment in the same function.
