368f045de1 [InstCombine] Refactor out OptimizeOverflowCheck. NFCI.
Summary:
This patch adds an enum `OverflowCheckFlavor` and a function
`OptimizeOverflowCheck`.  This will allow InstCombine to optimize
overflow checks without directly introducing an intermediate call to the
`llvm.$op.with.overflow` instrinsics.

This specific change is a refactoring and does not intend to change
behavior.

593fcb4854 LiveInterval: Fix computeFromMainRange() producing adjacent segments with same valno
If two livesegments from different subranges happened to have the same
definition they could possibly end up as two adjacent segments in the
main liverange with the same value number which is not allowed. Detect
such cases and fix them in the 2nd pass of computeFromMainRange() if
necessary.

No testcase as there is only an out-of-tree target where I can sensibly
come up with one.

a787066317 R600/SI: Initial support for assembler and inline assembly
This is currently considered experimental, but most of the more
commonly used instructions should work.

So far only SI has been extensively tested, CI and VI probably work too,
but may be buggy.  The current set of tests cases do not give complete
coverage, but I think it is sufficient for an experimental assembler.

See the documentation in R600Usage for more information.

112102c7fe AArch64: disallow "fmov sD, #-0.0" during assembly.
We weren't checking the sign of the floating point immediate before translating
it to "fmov sD, wzr". Similarly for D-regs.

Technically "movi vD.2s, #0x80, lsl #24" would work most of the time, but it's
not a blessed alias (and I don't think it should be since people expect writing
sD to zero out the high lanes, and there's no dD equivalent). So an error it is.

a0834f1d87 [LoopAccesses] Allow analysis to complete in the presence of uniform stores
Both run-time pointer checking and the dependence analysis are capable
of dealing with uniform addresses. I.e. it's really just an orthogonal
property of the loop that the analysis computes.

Run-time pointer checking will only try to reason about SCEVAddRec
pointers or else gives up. If the uniform pointer turns out the be a
SCEVAddRec in an outer loop, the run-time checks generated will be
correct (start and end bounds would be equal).

In case of the dependence analysis, we work again with SCEVs. When
compared against a loop-dependent address of the same underlying object,
the difference of the two SCEVs won't be constant. This will result in
returning an Unknown dependence for the pair.

When compared against another uniform access, the difference would be
constant and we should return the right type of dependence
(forward/backward/etc).

The changes also adds support to query this property of the loop and
modify the vectorizer to use this.

The current crash reporting on Mac OS is only disabled via an environment variable.
This adds a boolean (default false) which can also disable crash reporting.

This shouldn't affect anything in-tree, as the OperandType users are

However, on the flip side, that + the fact that this is just hinting at

0d8314f6f3 AArch64: Don't lower ISD::SELECT to ISD::SELECT_CC
Instead of lowering SELECT to SELECT_CC which is further lowered later
immediately call the SELECT_CC lowering code. This is preferable
because:
- Avoids an unnecessary roundtrip through the legalization queues with
  an intermediate node.
- More importantly: Lowered operations get visited last leading to SELECT_CC
  getting visited with legalized operands and unlegalized ones for preexisting
  SELECT_CC nodes. This does not hurt the current code (hence no testcase) but
  is required for another patch I am working on.
