While implementing `operator<=>` for `string_view` (D130295) @philnik
pointed out `common_type` should be `type_identity`. Since it was an
existing issue that wasn't addressed.
This addresses the issue for both the new and existing equality and
comparison operators. The test is based on the example posted in

location of last non-debug instruction after which epilogue
instructions are insrted.

Refactor baremetal driver code to reduce the bespoke
additions and base class overrides.
This lets us use the per target runtimes like other clang
targets. E.g. clang -target armv7m-cros-none-eabi will now
be able to use the runtimes installed at
<resource_dir>/lib/armv7m-cros-none-eabi instead of the hardcoded
path <resource_dir>/lib/baremetal.
The older code paths should still continue to work as before if
<resource_dir>/lib/<tuple> does not exist.

There is a fix for the search procedure at `SourceManager::getFileIDLoaded`. It might return an invalid (not loaded) entry. That might cause clang/clangd crashes. At my case the scenario was the following:
- `SourceManager::getFileIDLoaded` returned an invalid file id for a non loaded entry and incorrectly set `SourceManager::LastFileIDLookup` to the value
- `getSLocEntry` returned `SourceManager::FakeSLocEntryForRecovery` introduced at [D89748](https://reviews.llvm.org/D89748).
- The result entry is not tested at `SourceManager::isOffsetInFileID`and as result the call `return SLocOffset < getSLocEntryByID(FID.ID+1).getOffset();` returned `true` value because `FID.ID+1` pointed to a non-fake entry
- The tested offset was marked as one that belonged to the fake `SLockEntry`
Such behaviour might cause a weird clangd crash when preamble contains some header files that were removed just after the preamble created. Unfortunately it's not so easy to reproduce the crash in the form of a LIT test thus I provided the fix only.

We recently added support for multi-architecture binaries in
libomptarget. This is done by extracting the architecture from the
embedded image and comparing it with the major and minor version
supported by the current CUDA installation. Previously we just compared
these directly, which was not correct for binary compatibility. The CUDA
documentation states that we can consider any image with an equivalent
major or a greater or equal to minor compatible with the current image.
Change the check to use this new logic in the CUDA plugin.

SPE doesn't have a fmadd instruction, so don't bother hoisting a

Hoisting happens too late for the CTR usability test to veto using the

From the opengroup specifications, atan2 may fail if the result
underflows and atan may fail if the argument is subnormal, but
we assume that does not happen and eliminate the calls if we

Previously the language extension documentation didn't mention SVE and
was incomplete in listing the C/C++ operators supported on NEON. This
corrects the documentation to be in line with the implementation.
This patch adds the ability to context-sensitively analyze constructor bodies, by changing `pushCall` to allow both `CallExpr` and `CXXConstructExpr`, and extracting the main context-sensitive logic out of `VisitCallExpr` into a new `transferInlineCall` method which is now also called at the end of `VisitCXXConstructExpr`.

canCreateUndefOrPoison currently only handles unary ops, but we intend to change that soon - this more closely matches the pushFreezeToPreventPoisonFromPropagating behaviour where the freeze is pushed up to a single operand value, as long as all others are guaranteed not to be poison/undef.
However, pushFreezeToPreventPoisonFromPropagating would freeze all uses of the value - whilst this variant requires the frozen value to be only used in the op - we can look at generalize multiple uses later if the need arises.
We don't want the DEFINE_ macros or the array registers
being clang formatted.
RegisterInfos_arm64.h was missing the off annotation and
RegisterInfos_arm64_sve.h needed the off moving to before

Currently fcopysign for VLS vectors lowers through NEON even when the

Prior to this patch, libcalls inserted by the SelectionDAG legalizer
could never be tailcalled. The eligibility of libcalls for tail calling
is is partly determined by checking TargetLowering::isInTailCallPosition
and comparing the return type of the libcall and the calleer.
isInTailCallPosition in turn calls TargetLowering::isUsedByReturnOnly
(which always returns false if not implemented by the target).
This patch provides a minimal implementation of
TargetLowering::isUsedByReturnOnly - enough to support tail calling
libcalls on hard float ABIs. Soft-float ABIs are left for a follow on
patch. libcall-tail-calls.ll also shows missed opportunities to tail
call integer libcalls, but this is due to issues outside of
the isUsedByReturnOnly hook.

WebAssembly globals are represented as IR globals with the wasm_var
address space (AS1). Prior to this patch, a wasm global load that isn't
lowerable will produce a failure to select, while a wasm global store
will produced incorrect code. This patch ensures we consistently produce
a clear error.
As noted in the test cases, it's conceivable that a frontend or an
optimisation pass could produce similar IR even in the presence of the
semantic restrictions on pointers to Wasm globals in the frontend, which
is a separate problem to address.
