Use castAs as we know the cast should succeed (and castAs will assert if it doesn't) and we're dereferencing it directly in the canAssignObjCInterfaces call.
Most clients of SourceManager.h need to do things like turning source
locations into file & line number pairs, but this doesn't require
bringing in FileManager.h and LLVM's FS headers.
The main code change here is to sink SM::createFileID into the cpp file.
I reason that this is not performance critical because it doesn't happen
on the diagnostic path, it happens along the paths of macro expansion
(could be hot) and new includes (less hot).
Saves some includes:

Device-side compilation does not support some features and we need to
filter them out when command line options enable them for the host.
We're already doing this in various places in the regular clang driver,
but clang-cl mode constructs cc1 options independently and needs to
implement the filtering, too.

Module.h takes 86ms to parse, mostly parsing the class itself. Avoid it
if possible. ASTContext.h depends on ExternalASTSource.h.
A few NFC changes were needed to make this possible:
- Move ASTSourceDescriptor to Module.h. This needs Module to be
complete, and seems more related to modules and AST files than
external AST sources.
- Move "import complete" bit from Module* pointer int pair to
NextLocalImport pointer. Required because PointerIntPair<Module*,...>
requires Module to be complete, and now it may not be.

This matches the GCC behavior.
We track the enclosing template depth when determining whether a
statement expression is within a dependent context; there doesn't appear
to be any other reliable way to determine this.
We previously assumed they were neither value- nor
instantiation-dependent under any circumstances, which would lead to
crashes and other misbehavior.
We would assign the incorrect DeclContext when transforming the RequiresExprBodyDecl, causing incorrect
handling of 'this' inside RequiresExprBodyDecls (bug #45162).
Assign the current context as the DeclContext of the transformed decl.

Summary:
This patch generalizes the existing code to support CDE intrinsics
which will share some properties with existing MVE intrinsics
(some of the intrinsics will be polymorphic and accept/return values
of MVE vector types).
Specifically the patch:
* Adds new tablegen backends -gen-arm-cde-builtin-def,
-gen-arm-cde-builtin-codegen, -gen-arm-cde-builtin-sema,
-gen-arm-cde-builtin-aliases, -gen-arm-cde-builtin-header based on
existing MVE backends.
* Renames the '__clang_arm_mve_alias' attribute into
'__clang_arm_builtin_alias' (it will be used with CDE intrinsics as
well as MVE intrinsics)
* Implements semantic checks for the coprocessor argument of the CDE
intrinsics as well as the existing coprocessor intrinsics.
* Adds one CDE intrinsic __arm_cx1 to test the above changes

dependent constructs.
We previously assumed they were neither value- nor
instantiation-dependent under any circumstances, which would lead to
crashes and other misbehavior.
This doesn't match GCC's behavior (where statement expressions appear to
be treated as value-dependent if they appear in a dependent context),
but seems to be the best thing we can do in the short term: it turns out
to be remarkably difficult for us to correctly determine whether we are
in a dependent context (and it's not even possible in some cases, such
as in a generic lambda where we might not have seen the 'auto' yet).
This was previously reverted in 8e4a867 for rejecting some code, but that
code was invalid and Clang was previously incorrectly accepting it.
HIP emits a device stub function for each kernel in host code.
The HIP debugger requires device stub function to have a different unmangled name as the kernel.
Currently the name of the device stub function is the mangled name with a postfix .stub. However,
this does not work with the HIP debugger since the unmangled name is the same as the kernel.
This patch adds prefix __device__stub__ to the unmangled name of the device stub before mangling,
therefore the device stub function has a valid mangled name which is different than the device kernel
name. The device side kernel name is kept unchanged. kernels with extern "C" also gets the prefix added
to the corresponding device stub function.

After a first attempt to fix the test-suite failures, my first recommit
caused the same failures again. I had updated CMakeList.txt files of
tests that needed -fcommon, but it turns out that there are also
Makefiles which are used by some bots, so I've updated these Makefiles
now too.

This adds infrastructure for a multiversioning whitelist, plus adds
'used' to the allowed list with 'target'. The behavior here mirrors the
implementation in GCC, where 'used' only applies to the single
declaration and doesn't apply to the ifunc or resolver.
This is not being applied to cpu_dispatch and cpu_specific, since the
rules are more complicated for cpu_specific, which emits multiple
symbols. Additionally, the author isn't currently aware of uses in the
wild of this combination, but is aware of a number of target+used
combinations.
RebuildLambdaScopeInfo
Previously the type of the variable was being passed, which was causing
clang to crash when a non-reference variable was captured by reference
or a reference variable was captured by value by a lambda and a block
nested inside the lambda body was referencing the variable.
