[libcxx] Install ninja in CI container from system repo (#168225)
To fix the TODO now that the ninja version available in the Ubuntu
repositories (1.11) is new enough.
[CodeGen] Turn MCRegUnit into an enum class (NFC) (#167943)
This changes `MCRegUnit` type from `unsigned` to `enum class : unsigned`
and inserts necessary casts.
The added `MCRegUnitToIndex` functor is used with `SparseSet`,
`SparseMultiSet` and `IndexedMap` in a few places.
`MCRegUnit` is opaque to users, so it didn't seem worth making it a
full-fledged class like `Register`.
Static type checking has detected one issue in
`PrologueEpilogueInserter.cpp`, where `BitVector` created for
`MCRegister` is indexed by both `MCRegister` and `MCRegUnit`.
The number of casts could be reduced by using `IndexedMap` in more
places and/or adding a `BitVector` adaptor, but the number of casts *per
file* is still small and `IndexedMap` has limitations, so it didn't seem
worth the effort.

[X86] LowerMUL - remove vXi8 UNPCK(BUILD_VECTOR,UNDEF) special case handling (#168277)
getUnpackl/h + shuffle combining can now handle this for us generically
[DAG] Add baseline test coverage for #161036 (#168278)
Baseline tests from #161651 that were reverted in #167854
Still missing test coverage for the ffmpeg regression failures
[clang] Proofread *.rst (#168215)
This patch is limited to single-word replacements to fix spelling
and/or grammar to ease the review process. Punctuation and markdown
fixes are specifically excluded.
[ADT] Simplify DenseMap::grow (NFC) (#168238)
This patch simplifies DenseMap::grow by reimplementing it in terms of
DenseMapBase::moveFrom.
Since moveFrom iterates over the bucket range, we don't need:
if (!OldBuckets)
The old bucket array is released by the destructor on Tmp.
This patch removes moveFromOldBuckets as it's no longer used with this
patch. moveFromImpl is "inlined" into moveFrom.
[SelectionDAG] Verify SDTCisVT and SDTCVecEltisVT constraints (#150125)
Teach `SDNodeInfoEmitter` TableGen backend to process `SDTypeConstraint`
records and emit tables for them. The tables are used by
`SDNodeInfo::verifyNode()` to validate a node being created.
This PR only adds validation code for `SDTCisVT` and `SDTCVecEltisVT`
constraints to keep it smaller.

[X86] Avoid extra (PMADDUBSW(X,AND(Y)) in <X x i8> multiplication (#168262)
On SSSE3 targets we use PMADDUBSW of odd/even with suitable masking to
avoid having to extend/truncate with `<X x i16>` types and avoid
additional Port0/5 pressure.
However, lower i8 elements in the pair can safely use PMULLW directly
without any pre-masking as we will only use the lower i8 bits of the
result which is only affected by the lower i8 of the inputs.
[Polly] Remove ScopPass infrastructure (#125783)
PR #125442 replaces the pass-based Polly architecture with a monolithic
pass consisting of phases. Reasons listed in
https://github.com/llvm/llvm-project/pull/125442.
With this change, the SCoP-passes became redundant problematic versions
of the same functionality and are removed.
[LV] Check debug location for more recipes in vplan-printing.ll.
Extend test to check printing of debug locations to cover a range of
wide and replicating recipes. Currently those do not print the debug
metadata.
[AArch64][test] Improve pr166870.ll test case (#168194)
As pointed out in post-commit discussion on #167336
<https://github.com/llvm/llvm-project/pull/167336#issuecomment-3523794206>,
although the test case succeeds in showing a codegen difference now the
faulty MachineCopyPropagation logic was removed, the example was reduced
so much that it actually would have been legal to remove the seemingly
redundant mov.
This is a re-reduction of that test case which should now demonstrate a
mov that can't safely be removed (mov w9, w9) because the upper bits no
longer being zeroed may alter the program logic.
[NFC][clang] Correct bswapg test to work when int128 is not available (#168261)
This updates the test to avoid inclusion of int128 bswapg tests on
targets that don't support int128 at all.
This fixes failures introduced by #162433

Reapply "[compiler-rt] Default to Lit's Internal Shell" (#168232)
This reverts commit 8cc49fb99a4798f67b6b70fabfd584095d022e92.
This was causing failures on two specific buildbots that have since been
fixed.
