CGP can move instructions like a ptrtoint into a loop, but the
MVETailPredication when converting them will currently assume invariant
trip counts. This tries to ensure the operands are loop invariant, and
bails if not.

Initial (D96045) patch didn't handle split dwarf cases,
so this fixes that bug.
In addition, before applying this patch, we had a slowdown
that happened after the D96045. With this patch,
the slowdown will be fixed as well.

Add option to `clang-scan-deps` to enable/disable generation of command-line arguments with absolute paths. This is essentially a revert of D100533, but with improved naming and added test.

We have several extensions that need i32 to be Custom for
INTRINSIC_WO_CHAIN with RV64 so enable it for all RV64.
For V extension, make i32 Custom for RV64 and i64 Custom for RV32.
When the i32 or i64 is legal, the operation action doesn't matter.
LegalizeDAG checks MVT::Other rather than the real type.
This teaches DAG combine that shift amount operands for grev, gorc
shfl, unshfl only read a few bits.
This also teaches DAG combine that grevw, gorcw, shflw, unshflw,
bcompressw, bdecompressw only consume the lower 32 bits of their
inputs.
In the future we can teach SimplifyDemandedBits to also propagate
demanded bits of the output to the inputs in some cases.
https://reviews.llvm.org/D99400 set clang DefaultDebuggerTuning for AIX
to dbx. However, we still need to update the target default so that llc
and other tools will get the same default debuggertuning, and avoid
passing extra options in LTO.

In EHFrameRegistrationPlugin::notifyTransferringResources if SrcKey had
eh-frames associated but DstKey did not we would create a new entry for DskKey,
invalidating the iterator for SrcKey in the process. This commit fixes that by
removing SrcKey first in this case.
`X86TTIImpl::getInterleavedMemoryOpCostAVX2()` currently contains data
only for a handful of tuples. For now, at least add tests for a few more.
I'm guessing that we care how well the patterns codegen since
we use their presumed cost for vectorization decisions,
so i've added codegen tests too.
There's one really easy caveat for these codegen tests:
for interleaved load tests, we really have to ensure that the
deinterleaved vectors are escaped separately. Similarly for stores.
Bootstrap with `-Werror` is currently broken due to D79714.
This patch is required to bring the bootstrap bot back to green. The
code will likely need to be fixed and the pragmas removed in due time,
but for now we need to bring the bot back up.

Try to fix bug 49974.
This patch fixes two issues:
1. BL does not use predicate (BL_pred is the predicate version of BL),
so we shouldn't add predicate operands in DecodeBranchImmInstruction.
2. Inside DecodeT2AddSubSPImm, we shouldn't add predicate operands into
the MCInst because ARMDisassembler::AddThumbPredicate will do that for us.
However, we should handle CC-out operand for t2SUBspImm and t2AddspImm.

This patch adds a blocksOnly helpers which take an iterator range
over VPBlockBase * or const VPBlockBase * and returns an interator
range that only include BlockTy blocks. The accesses are casted to

The StringView::substr now accepts a substring starting position and its
length instead of previous non-standard `from` & `to` positions.
All uses of two argument StringView::substr are in MicrosoftDemangler
and have 0 as a starting position, so no changes are necessary.
This also fixes a bug where attempting to extract a suffix with substr
(a `to` position equal to size) would return a substring without the
last character.
Fixing the issue should not introduce observable changes in the
demangler, since as currently used, a second argument to
StringView::substr is either: 1) a result of a successful call to
StringView::find and so necessarily smaller than size., or 2) in the
case of Demangler::demangleCharLiteral potentially equal to size, but
with demangler expecting more data to follow later on and failing either
way.

During the review of D97115 it was mentioned adding the `<utility>`
header for `__to_underlying` was a bit unfortunate. Nowadays we tend to
implement smaller headers, so a good reason to move `std::to_underlying`
to its own header and adjust `<charconv>` to use the new header.

We only apply `clang_builtin_alias` to non-masked builtins.
Masked builtins could not use `clang_builtin_alias` because the
operand order is different between overloaded intrinsics and builtins.
A bunch of test cases need to be updated.
