142446e535 Pull in r300429 from upstream llvm trunk (by Benjamin Kramer):
[X86] Remove special handling for 16 bit for A asm constraints.

  Our 16 bit support is assembler-only + the terrible hack that is
  .code16gcc. Simply using 32 bit registers does the right thing for
  the latter.

  Fixes PR32681.

This fixes some cases of assembling 16 bit code (i.e. SeaBIOS) that uses
the 'A' inline asm constraint, after r316989.

86a34ce5a4 Pull in r300404 from upstream llvm trunk (by me):
Use correct registers for "A" inline asm constraint

  Summary:
  In PR32594, inline assembly using the 'A' constraint on x86_64 causes
  llvm to crash with a "Cannot select" stack trace.  This is because
  `X86TargetLowering::getRegForInlineAsmConstraint` hardcodes that 'A'
  means the EAX and EDX registers.

  However, on x86_64 it means the RAX and RDX registers, and on 16-bit
  x86 (ia16?) it means the old AX and DX registers.

  Add new register classes in `X86RegisterInfo.td` to support these
  cases, and amend the logic in `getRegForInlineAsmConstraint` to cope
  with different subtargets.  Also add a test case, derived from
  PR32594.

095282cf35 Reapply r287232 from upstream llvm trunk (by Daniil Fukalov):
[SCEV] limit recursion depth of CompareSCEVComplexity

  Summary:
  CompareSCEVComplexity goes too deep (50+ on a quite a big unrolled
  loop) and runs almost infinite time.

  Added cache of "equal" SCEV pairs to earlier cutoff of further
  estimation. Recursion depth limit was also introduced as a parameter.

Pull in r296992 from upstream llvm trunk (by Sanjoy Das):

  [SCEV] Decrease the recursion threshold for CompareValueComplexity

  Fixes PR32142.

  r287232 accidentally increased the recursion threshold for
  CompareValueComplexity from 2 to 32.  This change reverses that
  change by introducing a separate flag for CompareValueComplexity's
  threshold.

The latter revision fixes the excessive compile times for skein_block.c.

This commit is the cause of excessive compile times on skein_block.c
(and possibly other files) during kernel builds on amd64.

We never saw the problematic behavior described in this upstream commit,
so for now it is better to revert it.  An upstream bug has been filed
here: https://bugs.llvm.org/show_bug.cgi?id=32142

c819c1240d Pull in r293773 from upstream llvm trunk (by Sanjay Patel):
[ValueTracking] avoid crashing from bad assumptions (PR31809)

  A program may contain llvm.assume info that disagrees with other
  analysis. This may be caused by UB in the program, so we must not
  crash because of that.

  As noted in the code comments:
  https://llvm.org/bugs/show_bug.cgi?id=31809
  ...we can do better, but this at least avoids the assert/crash in the
  bug report.

Fix use-after-free bug in AffectedValueCallbackVH::allUsesReplacedWith

  When transferring affected values in the cache from an old value,
  identified by the value of the current callback, to the specified new
  value we might need to insert a new entry into the DenseMap which
  constitutes the cache. Doing so might delete the current callback
  object. Move the copying logic into a new function, a member of the
  assumption cache itself, so that we don't run into UB should the
  callback handle itself be removed mid-copy.
