David Blaikie c7aaacde67 Allow Optionals to be compared to None
This is something like nullopt in std::experimental::optional. Optional
could already be constructed from None, so this seems like an obvious
extension from there.

I have a use in a future patch for Clang, though it may not go that
way/end up used - so this seemed worth committing now regardless.

John McCall 0d461693b6 Fix the layout of bitfields in ms_struct unions: their
alignment is ignored, and they always allocate a complete
storage unit.

Also, change the dumping of AST record layouts: use the more
readable C++-style dumping even in C, include bitfield offset
information in the dump, and don't print sizeof/alignof
information for fields of record type, since we don't do so
for bases or other kinds of field.

Alexander Kornienko 1b7bf7a2a7 [clang-tidy] Add modernize-use-nullptr check, attempt 2.
This patch re-applies r245434 and r245471 reverted in r245493, and changes the
way custom null macros are configured. The test for custom null macros is
temporarily excluded and will be committed separately to reduce chances of
breakages.

Juergen Ributzka b12248e9cd [AArch64][FastISel] Don't fold shifts with UB.
We are already falling back to SelectionDAG when encountering an shift with UB.

David Majnemer f25fe64716 [X86] Emit more efficient >= comparisons against 0
We don't do a great job with >= 0 comparisons against zero when the
result is used as an i8.

Given something like:
  void f(long long LL, bool *B) {

Dan Gohman dde8dce6a9 [WebAssembly] Use the default alignment for SIMD types.
Previously WebAssembly's datalayout string had -v128:8:128. This had been an
attempt to declare a certain level of support for unaligned SIMD accesses.
However, clang makes its own determinations for SIMD alignment that are
independent of the datalayout string, so this wasn't actually meaningful.

This revision has introduced an issue that only affects bootstrapped compiler

Alex Lorenz e66a7ccf77 MIR Serialization: Serialize defined registers that require 'def' register flag.
The defined registers are already serialized - they are represented by placing
them before the '=' in a machine instruction. However, certain instructions like
INLINEASM can have defined register operands after the '=', so this commit
introduces the 'def' register flag for such operands.

Bruno Cardoso Lopes 27fd06922b [PeepholeOptimizer] Look through PHIs to find additional register sources
Reintroduce r245442. Remove an overly conservative assertion introduced
in r245442. We could replace the assertion to use `shareSameRegisterFile`
instead, but in that point in `insertPHI` we already lost the original
Def subreg to check against. So drop the assertion completely.

Original commit message:

- Teaches the ValueTracker in the PeepholeOptimizer to look through PHI
instructions.
- Add findNextSourceAndRewritePHI method to lookup into multiple sources
returnted by the ValueTracker and rewrite PHIs with new sources.

With these changes we can find more register sources and rewrite more
copies to allow coaslescing of bitcast instructions. Hence, we eliminate
unnecessary VR64 <-> GR64 copies in x86, but it could be extended to
other archs by marking "isBitcast" on target specific instructions. The
x86 example follows:

A:
  psllq %mm1, %mm0
  movd  %mm0, %r9
  jmp C

B:
  por %mm1, %mm0
  movd  %mm0, %r9
  jmp C

C:
  movd  %r9, %mm0
  pshufw  $238, %mm0, %mm0

Becomes:

A:
  psllq %mm1, %mm0
  jmp C

B:
  por %mm1, %mm0
  jmp C

C:
  pshufw  $238, %mm0, %mm0
