LLVM is recommending to use SmallVector (that is, omitting the N), in the
absence of a well-motivated choice for the number of inlined elements N.
However, this doesn't work well with XL compiler on AIX since some header(s)
aren't properly picked up with it. We need to take a further look into the real
issue underneath and fix it in a later patch.
But currently we'd like to use this patch to unblock the build compiler issue
first.

AMDGPU target tries to handle the SGPR and VGPR spills in a
custom pass before the actual frame lowering pass. Once they
are handled and the respective frames are eliminated in the
custom pass, certain uses of them still remain. For instance,
the DBG_VALUE instructions inserted by the allocator alongside
the spill instruction will use the corresponding frame index.
They become dead later during PEI and causes a crash while trying to
replace the frame indices. We should possibly avoid this custom pass.
For now, replacing such dead references with null register value.

All extractvalues of the same value at the same index will map to

The LiveDebugValues and LiveDebugVariables implementations for handling
DBG_VALUE_LIST instructions can be simplified significantly if they do not have

duplicated operands.

I've included tests that require type legalization to split the
vector. The i64 version of these scalarizes on RV32 due to type
legalization visiting the result before the vector type. So we
have to abort our custom expansion to avoid creating target
specific nodes with an illegal type. Then type legalization ends
up scalarizing. We might be able to fix this by doing custom
splitting for large vectors in our handler to get down to a legal
type.

The default fixed vector expansion uses sra+xor+add since it can't
see that smax is legal due to our custom handling. So we select
smax(X, sub(0, X)) manually.
Scalable vectors are able to use the smax expansion automatically
for most cases. It crashes in one case because getConstant can't build a
SPLAT_VECTOR for nxvXi64 when i64 scalars aren't legal. So
we manually emit a SPLAT_VECTOR_I64 for that case.

As far as I know we're not enforcing the StdExtM must be enabled
to use the V extension. If we use an assert here and hit this

By using a diagnostic we report the error to the user in release

This patch updates the various IR passes to correctly handle dbg.values with a
DIArgList location. This patch does not actually allow DIArgLists to be produced
by salvageDebugInfo, and it does not affect any pass after codegen-prepare.
Other than that, it should cover every IR pass.
Most of the changes simply extend code that operated on a single debug value to
operate on the list of debug values in the style of any_of, all_of, for_each,
etc. Instances of setOperand(0, ...) have been replaced with with
replaceVariableLocationOp, which takes the value that is being replaced as an
additional argument. In places where this value isn't readily available, we have
to track the old value through to the point where it gets replaced.

For clang this change is NFC cleanup, because clang
never calls atomic functions from runtime library.
Basically, pause is good in spin-loops waiting for something.
Atomic CAS loops do not wait for anything,
each CAS failure means some other thread progressed.
Performance experiments show that the pause only causes unnecessary slowdown
on CPUs with slow pause instruction, no difference on CPUs with fast pause
instruction, removal of the pause gives lesser binary size which is good.

This patch refactors include-module.f90:
* rename the test file as use-module.f90 to better highlight which
driver feature is being tested
* move tests for diagnostics to use-module-error.f90 (it tests that
`-J/-module-dir` can only be used once)
* make sure that `f18` is tested when `FLANG_BUILD_NEW_DRIVER` is
set to `Off`
* add tests for when all module files are successfully discovered and
loaded
With this patch, there should be a clear separation into 3 scenarios in
use-module.f90:
* Everything is OK
* One module file wasn't found (missing include path for
basictestingmoduletwo.mod)
* Two module files are found, but the test requires
`basictestingmoduleone.mod` from both `Inputs` and `Inputs/module-dir`.
Only the latter is found.

This provides a nice thread-safe interface for using dirty file contents throughout the codebase, for example cross file refactoring.
Creating a Filesystem view will overlay a snapshot of the current contents, so if the draft store is updated while the view is being used, it will contain stale contents.

The path iterator macros don't support that.
Use a temporary variable to ensure everything points to a single string.

This patch implements the conditional select operator for
ext_vector_types in C++. It does so by using the same semantics as for
C.
D71463 added support for the conditional select operator for VectorType
in C++. Unfortunately the semantics between ext_vector_type in C are
different to VectorType in C++. Select for ext_vector_type is based on
the MSB of the condition vector, whereas for VectorType it is `!= 0`.
This unfortunately means that the behavior is inconsistent between
ExtVectorType and VectorType, but I think using the C semantics for
ExtVectorType in C++ as well should be less surprising for users.

SDDbgValues with multiple location operands to be emitted as DBG_VALUE_LIST
instructions.
The primary change of this patch is refactoring EmitDbgValue by pulling location
operand emission out to the new function AddDbgValueLocationOps, which is used
for both DIArgList and single value dbg.values. Outside of that, the only
behaviour change is that the scheduler has a lambda added, HasUnknownVReg, to
prevent us from attempting to emit a DBG_VALUE_LIST before all of its used VRegs
have become available.

If the incoming values of a phi are pointer casts of the same original
value, replace the phi with a single cast. Such redundant phis are
somewhat common after loop-rotate and removing them can avoid some
unnecessary code bloat, e.g. because an iteration of a loop is peeled
off to make the phi invariant. It should also simplify further analysis
on its own.
InstCombine already uses stripPointerCasts in a couple of places and
also simplifies phis based on the incoming values, so the patch should
fit in the existing scope.

This was causing TSan failures due to a race on vptr during destruction,
see
https://lab.llvm.org/buildbot/#/builders/131/builds/6579/steps/6/logs/FAIL__Clangd_Unit_Tests__LSPTest_FeatureModulesThr.
The story is, during the execution of a destructor all the virtual
dispatches should resolve to implementations in the class being
destroyed, not the derived ones. And LSPTests will log some stuff during
destruction (we send shutdown/exit requests, which are logged), which is
a virtual dispatch when LSPTest is derived from clang::clangd::Logger.
It is a benign race in our case, as gtests that derive from LSPTest
doesn't override the `log` method. But still during destruction, we
might try to update vtable ptr (due to being done with destruction of
test and starting destruction of LSPTest) and read from it to dispatch a
log message at the same time.
This patch fixes that race by moving `log` out of the vtable of
`LSPTest`.
