This is another attempt to address the issue introduced in
ae8b2cab67.
We cannot capture InstalledDir because FileCheck doesn't handle
the backslashes correctly, so instead we just consume the entire
path prefix which is what other tests are doing.
Darwin driver currently uses libc++ headers that are part of Clang
toolchain when available (by default ../include/c++/v1 relative to
executable), but it completely ignores the libc++ library itself
because it doesn't pass the location of libc++ library that's part
of Clang (by default ../lib relative to the exceutable) to the linker
always using the system copy of libc++.
This may lead to subtle issues when the compilation fails because the
headers that are part of Clang toolchain are incompatible with the
system library. Either the driver should ignore both headers as well as
the library, or it should always try to use both when available.
This patch changes the driver behavior to do the latter which seems more
reasonable, it makes it easy to test and use custom libc++ build on
Darwin while still allowing the use of system version. This also matches
the Clang driver behavior on other systems.

Looking at the Doxygen-generated documentation for the clang namespace
currently shows several random comments from different parts of the
codebase. These are caused by:
- File doc comments that aren't marked with \file, so they're attached to
the next declaration, which is usually "namespace clang {".
- Class doc comments placed before the namespace rather than before the
class.
This commit fixes these comments. The generated doxygen documentation now
has proper docs for several classes and files, and the docs for the clang
namespace is now empty.

This demotes the apple-a12 CPU selection for arm64e to just be the
last-resort default. Concretely, this means:
- an explicitly-specified -mcpu will override the arm64e default;
a user could potentially pick an invalid CPU that doesn't have
v8.3a support, but that's not a major problem anymore
- arm64e-apple-macos (and variants) will pick apple-m1 instead of
being forced to apple-a12.
apple-m1 has the same level of ISA support as apple-a14,
so this is a straightforward mechanical change. However, that
also means this inherits apple-a14's v8.5a+nobti quirkiness.

As reported in PR50025, sometimes we would end up not emitting functions
needed by inline multiversioned variants. This is because we typically
use the 'deferred decl' mechanism to emit these. However, the variants
are emitted after that typically happens. This fixes that by ensuring
we re-run deferred decls after this happens. Also, the multiversion
emission is done recursively to ensure that MV functions that require
other MV functions to be emitted get emitted.
Previously, clang-format would erroneously merge import and export
statements. These need to be kept separate, as the semantics differ.

The NSS FileCheck variables at the end of the
CodeGenCXX/split-stacks.cpp clang testcase are off by 1, resulting in
the use of an undefined variable (NSS3). One of the CHECK-NOT is also

This patch simplifies (and renames) the `appendCommonModuleArguments` function.
It no longer tries to construct the command line for explicitly building modules. Instead, it only performs the DFS traversal of modular dependencies and queries the callbacks to collect paths to `.pcm` and `.modulemap` files.
This makes it more flexible and usable in two contexts:
* Generating additional command line arguments for the main TU in modular build. The `std::vector<std::string>` output parameters can be used to manually generate appropriate command line flags.
* Generate full command line for a module. The output parameters can be the corresponding parts of `CompilerInvocation`. (In a follow-up patch.)

Instead of using a MinVersion and MaxVersion field, encode the version
of a builtin using a mask that aligns better with version handling in
OpenCLOptions.h. In addition, this saves a field in the BuiltinTable.
This change allows a finer-grained control over the OpenCL versions in
which a builtin is available: instead of a range, we can now toggle
each version individually.
The fine-grained version control is not yet exposed on the TableGen
definitions side, as changes for OpenCL 3 feature optionality still
need to be defined and will affect how we want to expose these.

The commited patch broke mlir tests. It seems that mlir tests depend on coroutine function properties set in CoroEarly pass.
Presplit coroutines cannot be inlined. During AlwaysInliner we check if a function is a presplit coroutine, if so we skip inlining.
The presplit coroutine attributes are set in CoroEarly pass.
However in O0 pipeline, AlwaysInliner runs before CoroEarly, so the attribute isn't set yet and will still inline the coroutine.
This causes Clang to crash: https://bugs.llvm.org/show_bug.cgi?id=49920
To fix this, we set the attributes in the Clang front-end instead of in CoroEarly pass.

Extend the matchers gathering API for types to record template
parameters. The TypeLoc type hierarchy has some types which are
templates used in CRTP such as PointerLikeTypeLoc. Record the inherited
template and template arguments of types inheriting those CRTP types in
the ClassInheritance map. Because the name inherited from is now
computed, the value type in that map changes from StringRef to
std::string. This also causes the toJSON override signature used to
serialize that map to change.
Remove the logic for skipping over empty ClassData instances. Several
classes such as TypeOfExprTypeLoc inherit a CRTP class which provides
interesting locations though the derived class does not. Record it as a
class to make the locations it inherits available.
Record the typeSourceInfo accessors too as they provide access to
TypeLocs in many classes.
The existing unit tests use UnorderedElementsAre to compare the
introspection result with the expected result. Our current
implementation of google mock (in gmock-generated-matchers.h) is limited
to support for comparing a container of 10 elements. As we are now
returning more than 10 results for one of the introspection tests,
change it to instead compare against an ordered vector of pairs.
Because a macro is used to generate API strings and API calls, disable
clang-format in blocks of expected results. Otherwise clang-format
would insert whitespaces which would then be compared against the
introspected strings and fail the test.
Introduce a recursion guard in the generated code. The TypeLoc class
has IgnoreParens() API which by default returns itself, so it would
otherwise recurse infinitely.

This class initially had args to be generic to future needs. In
particular, I thought that source location introspection should show the
getBeginLoc of CallExpr args and the getArgLoc of

out of source location introspection because it involves node traversal.
If something like this is needed in the future, it can be added in the

hipRTC compiles HIP device code at run time. Since the system may not
have development tools installed, when a HIP program is compiled through
hipRTC, there is no standard C or C++ header available. As such, the HIP
headers should not depend on standard C or C++ headers when used
with hipRTC. Basically when hipRTC is used, HIP headers only provides
definitions of HIP device API functions. This is in line with what nvRTC does.
This patch adds support of hipRTC to HIP headers in clang. Basically hipRTC
defines a macro __HIPCC_RTC__ when compile HIP code at run time. When
this macro is defined, HIP headers do not include standard C/C++ headers.
