NOTE: some files are being removed from those files that are clang-formatted
which means some lack of formatting is slipping through the net on reviews
Some of the first supported version field were incorrectly attributed to a later branch.
It wasn't possible to correctly determine the "introduced version" with my naive implementation
using git blame alone, (especially if the type had been changed from a bool -> enum)
I saw more things attributed to clang-format 13 than I remembered and reviewed
those options to determine their introduced version.

It may be possible to avoid relying on accessing many individual class pages,
by instead scanning the class index page at
https://clang.llvm.org/doxygen/classes.html. This updates the script to do so,
and includes updates to `LibASTMatchersReference.html` generated by the

The current infrastructure in lib/Interpreter has a tool, clang-repl, very
similar to clang-interpreter which also allows incremental compilation.
This patch moves clang-interpreter as a test case and drops it as conditionally

This patch also ignores ppc due to missing weak symbol for __gxx_personality_v0
which may be a feature request for the jit infrastructure. Also, adds a missing
build system dependency to the orc jit.

Additionally, this patch defines a custom exception type and thus avoids the

This patch also works around PR49692 and finds a way to use llvm::consumeError

This change now generates that list, and the change to clang-format allows
us to run clang-format quickly over these files via the list of files.
clang-format.exe -verbose -n --files=./clang/docs/tools/clang-formatted-files.txt
```
Clang-formating 7926 files
Formatting [1/7925] clang/bindings/python/tests/cindex/INPUTS/header1.h
..
Formatting [7925/7925] utils/bazel/llvm-project-overlay/llvm/include/llvm/Config/config.h
```
This is needed because putting all those files on the command line is too
long, and invoking 7900+ clang-formats is much slower (too slow to be honest)
Using this method it takes on 7.5 minutes (on my machine) to run
`clang-format -n` over all of the files (7925), this should result in us
testing any change quickly and easily.
We should be able to use rerunning this list to ensure that we don't regress
clang-format over a large code base, but also use it to ensure none of the
previous files which were 100% clang-formatted remain so.
(which the LLVM premerge checks should be enforcing)

After significant problems in our downstream with the previous
implementation, the SYCL standard has opted to make using macros/etc to
change kernel-naming-lambdas in any way UB (even passively). As a
result, we are able to just emit the itanium mangling.
However, this DOES require a little work in the CXXABI, as the microsoft
and itanium mangler use different numbering schemes for lambdas. This
patch adds a pair of mangling contexts that use the normal 'itanium'
mangling strategy to fill in the "DeviceManglingNumber" used previously
by CUDA.

Sometimes I see people unsure about which options they can use in specific versions of clang-format because
https://clang.llvm.org/docs/ClangFormatStyleOptions.html points to the latest and greatest versions.
The reality is this says its version 13.0, but actually anything we add now, will not be in 13.0 GA but
instead 14.0 GA (as 13.0 has already been branched).
How about we introduce some nomenclature to the Format.h so that we can mark which options in the
documentation were introduced for which version?

This patch adds a new preprocessor extension ``#pragma clang final``
which enables warning on undefinition and re-definition of macros.
The intent of this warning is to extend beyond ``-Wmacro-redefined`` to
warn against any and all alterations to macros that are marked `final`.
This warning is part of the ``-Wpedantic-macros`` diagnostics group.

Developers these days seem to argue over east vs west const like they used to argue over tabs vs whitespace or the various bracing style. These previous arguments were mainly eliminated with tools like `clang-format` that allowed those rules to become part of your style guide. Anyone who has been using clang-format in a large team over the last couple of years knows that we don't have those religious arguments any more, and code reviews are more productive.
https://www.youtube.com/watch?v=fv--IKZFVO8https://mariusbancila.ro/blog/2018/11/23/join-the-east-const-revolution/https://www.youtube.com/watch?v=z6s6bacI424
The purpose of this revision is to try to do the same for the East/West const discussion. Move the debate into the style guide and leave it there!
In addition to the new `ConstStyle: Right` or `ConstStyle: Left` there is an additional command-line argument `--const-style=left/right` which would allow an individual developer to switch the source back and forth to their own style for editing, and back to the committed style before commit. (you could imagine an IDE might offer such a switch)
The revision works by implementing a separate pass of the Annotated lines much like the SortIncludes and then create replacements for constant type declarations.

Recently a vulnerability issue is found in the implementation of VLLDM
instruction in the Arm Cortex-M33, Cortex-M35P and Cortex-M55. If the
VLLDM instruction is abandoned due to an exception when it is partially
completed, it is possible for subsequent non-secure handler to access
and modify the partial restored register values. This vulnerability is
identified as CVE-2021-35465.
The mitigation sequence varies between v8-m and v8.1-m as follows:
v8-m.main

mrs r5, control
tst r5, #8 /* CONTROL_S.SFPA */

SelectionDAG will promote illegal types up to a power of 2 before
splitting down to a legal type. This will create an IntegerType
with a bit width that must be <= MAX_INT_BITS. This places an
effective upper limit on any type of 2^23 so that we don't try
create a 2^24 type.
I considered putting a fatal error somewhere in the path from
TargetLowering::getTypeConversion down to IntegerType::get, but
limiting the type in IR seemed better.
This breaks backwards compatibility with IR that is using a really
large type. I suspect such IR is going to be very rare due to the
the compile time costs such a type likely incurs.
Prevents the ICE in PR51829.

Earlier BundleEntryID used to be <OffloadKind>-<Triple>-<GPUArch>.
This used to work because the clang-offload-bundler didn't need
GPUArch explicitly for any bundling/unbundling action. With
unbundleArchive it needs GPUArch to ensure compatibility between
device specific code objects. D93525 enforced triples to have
separators for all 4 components irrespective of number of
components, like "amdgcn-amd-amdhsa--". It was required to
to correctly parse a possible 4th environment component or a GPU.
But, this condition is breaking backward compatibility with
archive libraries compiled with compilers older than D93525.
This patch allows triples to have any number of components with
and without extra separator for empty environment field. Thus,
both the following bundle entry IDs are same:
openmp-amdgcn-amd-amdhsa--gfx906
openmp-amdgcn-amd-amdhsa-gfx906
