A user pointed out to me in private email that this test will fail if
it sees the letter 's' followed by a digit in any part of clang's
assembly output after the function label. That includes the .ident at
the end, which can include a full pathname or hostname or both from
the system clang was built on. So if that path or hostname includes
any text like 's5' then it will cause the test to fail.
Fixed by adding a check for `.fnend`, to limit the scope of the
`CHECK-NOT` to only the actual generated code for the test function.
(Committed without prior review on the basis that it's a simple and
obvious pure test-suite fix and also in a test I contributed myself.)

Summary:
This fixes a regression that led to size() not being available in clangd
when completing 'deque().^' and using libc++.

We previously failed to treat an array with an instantiation-dependent
but not value-dependent bound as being an instantiation-dependent type.
We now track the array bound expression as part of a constant array type
if it's an instantiation-dependent expression.

This is a rare place where it's valid for a function type to be
substituted but not valid for a qualified function type to be
substituted, so needs a special check.

Some Driver tests relied on the default resource direcory having per-os per-arch
subdirectory layout, and when clang is built with `-DLLVM_ENABLE_PER_TARGET_RUNTIME_DIR=ON`,
those test fail, because clang by default assumes per-target subdirectories.
Explicitly set `-resource-dir` flag to point to a tree with per-os per-arch layout.

Sometimes it is useful to compile HIP device code to LLVM BC. It is not convenient to use clang -cc1 since
there are lots of options needed.
This patch allows clang driver to compile HIP device code to LLVM BC with -emit-llvm -c.

pointer-to-member call can't determine a callee.
We will have produced a diagnostic already if the callee is known to be
unevaluatable, and diagnosing here rejects valid code during potential
constant expression checking.

It appears there are some issues with the hexagon toolchain, and also the file

attempt a revert.

For now, we restrict this support to use from within the standard
library implementation, since we're required to make parts of the
standard library that use placement new work, but not permitted to
make uses of placement new from user code work.

This patch enables end to end support for generating ELF interface stubs
directly from clang. Now the following:
clang -emit-interface-stubs -o libfoo.so a.cpp b.cpp c.cpp
will product an ELF binary with visible symbols populated. Visibility attributes
and -fvisibility can be used to control what gets populated.
* Adding ToolChain support for clang Driver IFS Merge Phase
* Implementing a default InterfaceStubs Merge clang Tool, used by ToolChain
* Adds support for the clang Driver to involve llvm-ifs on ifs files.
* Adds -emit-merged-ifs flag, to tell llvm-ifs to emit a merged ifs text file
instead of the final object format (normally ELF)

Context selectors may include optional score clause in format
`score(<expr>):`, where `<expr>` must be a constant integer expression.

Summary:
when renaming a typedef decl, we used to rename the underlying decl of the
typedef, we should rename the typedef itself.

Summary:
To trigger the index-only Whole Program Devirt support added to LLVM, we
need to be able to specify -fno-split-lto-unit in conjunction with
-fwhole-program-vtables. Keep the default for -fwhole-program-vtables as
-fsplit-lto-unit, but don't error on that option combination.

Summary:
Clang uses the location identifier should be inserted for declarator
decls when a decl is unnamed. But for type template and template template
paramaters it uses the location of "typename/class" keyword, which makes it hard
for tooling to insert/change parameter names.
This change tries to unify these two cases by making template parameter
parsing and sourcerange operations similar to function params/declarator decls.

Some platforms (e.g. AArch64) put __va_list in the 'std' namespace which might
end up being the first namespace we match in this test. Instead let
the first namespace match via file name/line so that we skip the
builtin namespaces.

CallGraph visited LambdaExpr by getting the Call Operator from
CXXRecordDecl (LambdaExpr::getCallOperator calls
CXXRecordDecl::getLambdaCallOperator), which replaced generic lambda
call operators with the non-instantiated FunctionDecl. The result was
that the CallGraph would only pick up non-dependent calls.
This patch does a few things:
1- Extend CXXRecordDecl to have a getDependentLambdaCallOperator, which
will get the FunctionTemplateDecl, rather than immediately getting the
TemplateDecl.
2- Define getLambdaCallOperator and getDependentLambdaCallOperator in
terms of a common function.
3- Extend LambdaExpr with a getDependentCallOperator, which just calls
the above function.
4- Changes CallGraph to handle Generic LambdaExprs.
