`LLVM_DISTRIBUTION_COMPONENTS` now influences the llvm binary in the
normal cmake output directory when it is set. This allows for
distribution targets to only include tools they want in the llvm
binary. It must be done this way because only one target can be
associated with a specific output name.

This adds support under AArch64 for the target("..") attributes. The
current parsing is very X86-shaped, this patch attempts to bring it line
with the GCC implementation from
https://gcc.gnu.org/onlinedocs/gcc/AArch64-Function-Attributes.html#AArch64-Function-Attributes.
The supported formats are:
- "arch=<arch>" strings, that specify the architecture features for a
function as per the -march=arch+feature option.
- "cpu=<cpu>" strings, that specify the target-cpu and any implied
atributes as per the -mcpu=cpu+feature option.
- "tune=<cpu>" strings, that specify the tune-cpu cpu for a function as
per -mtune.
- "+<feature>", "+no<feature>" enables/disables the specific feature, for
compatibility with GCC target attributes.
- "<feature>", "no-<feature>" enabled/disables the specific feature, for
backward compatibility with previous releases.
To do this, the parsing of target attributes has been moved into
TargetInfo to give the target the opportunity to override the existing
parsing. The only non-aarch64 change should be a minor alteration to the
error message, specifying using "CPU" to describe the cpu, not
"architecture", and the DuplicateArch/Tune from ParsedTargetAttr have
been combined into a single option.

When a compound requirement is too long to fit onto a single line, the
braces are split apart onto separate lines, and the contained expression
is indented. However, this indentation would also apply to the closing
brace and the trailing return type requirement thereof.
This was because the indentation level was being restored after all
trailing things were already read
With this change, the initial level of the opening brace is set before
attempting to read any trailing return type requirements

Now that all jobs have moved over to the new style of Lit configuration,
we can remove all traces of the legacy testing configuration system.
This includes:
- Cache settings that are not honored or useful anymore
- Several CMake options that were only useful in the context of the
legacy Lit configuration system
- A bunch of Python support code that is not used anymore
- The legacy lit.cfg.in files themselves

Add support for a CLANG_NO_DEFAULT_CONFIG envvar that works like
the --no-default-config option when set to a non-empty value. Use it
to disable loading system configuration files during the test suite
runs.
Configuration files can change the driver behavior in extensive ways,
and it is neither really possible nor feasible to account for or undo
the effects of even the most common configuration uses. Therefore,
the most reasonable option seems to be to ignore configuration files
while running the majority of tests (with the notable exception of tests
for configuration file support).
Due to the diversity of ways that %clang is used in the test suite,
including using it to copy or symlink the clang executable, as well to
call -cc1 and -cc1as modes, it is not feasible to pass the explicit
options to disable config loading either. Using an environment variable
has the advantage of being easily applied across the test suite
and easily unset for default configuration file loading tests.

Disallow this meaningless combination. Doing so simplifies analysis
of LLVM code w.r.t t DLL storage-class, and prevents mistakes with
DLL storage class.
- Change the assembler to reject DLL storage class on symbols with
local linkage.
- Change the bitcode reader to clear the DLL Storage class when the
linkage is local for auto-upgrading
- Update LangRef.
There is an existing restriction on non-default visibility and local
linkage which this is modelled on.

This change exposes the ceil library function for HLSL,
excluding long, int, and long long doubles.
Ceil is supported for all scalar, vector, and matrix types.
Long and long long double support is missing in this patch because those types
don't exist in HLSL. Int is missing because the ceil function only works on floating type arguments.
The full documentation of the HLSL ceil function is available here:

This partially reverts commit 1609a5d771 (the
test/Driver part). We want to discourage %clang_cc1 and clang -cc1 in
test/Driver. The clang -cc1 uses in hlsl/offload/etc are not good examples.
Use the `%clang_cc1` substitution consistently across the test suite,
replacing inline `%clang -cc1` invocations, except for one Preprocessor
test where this is causing breakage. This is necessary to ensure that
additional parameters passed via `%clang` do not interfere with `-cc1`
that must always be passed as the first command-line argument.
Remove the additional substitution blocking `%clang_cc1` use in Driver
tests. It has been added in 2013 and was supposed to prevent tests
calling `clang -cc1` from being added to Driver. The state of the test
suite proves that it did not succeed at all.

Move the `%clang_dxc` substitution from local definition in clang/test

Change the default config file loading logic to be more flexible
and more readable at the same time. The new algorithm focuses on four
locations, in order:
1. <triple>-<mode>.cfg using real driver mode
2. <triple>-<mode>.cfg using executable suffix
3. <triple>.cfg + <mode>.cfg using real driver mode
4. <triple>.cfg + <mode>.cfg using executable suffix
This is meant to preserve reasonable level of compatibility with
the existing use, while introducing more flexibility and making the code
simpler. Notably:
1. In this layout, the actual target triple is normally respected,
and e.g. in `-m32` build the `x86_64-*` configs will never be used.
2. Both real driver mode (preferable) and executable suffix are
supported. This permits correctly handling calls with explicit
`--driver-mode=` while at the same time preserving compatibility
with the existing code.
3. The first two locations provide users with the ability to override
configuration per specific target+mode combinaton, while the next two
make it possible to independently specify per-target and per-mode
configuration.
4. All config file locations are applicable independently of whether
clang is started via a prefixed executable, or bare `clang`.
5. If the target is not explicitly specified and the executable prefix
does not name a valid triple, it is used instead of the actual target
triple for backwards compatibility.
This is particularly meant to address Gentoo's use case for
configuration files: to configure the default runtimes (i.e. `-rtlib=`,
`-stdlib=`) and `--gcc-install-dir=` for all the relevant drivers,
as well as to make it more convenient for users to override `-W` flags
to test compatibility with future versions of Clang easier.

There are lots of options interacting in complex ways here, and when moving to
`getDefaultUnwindTableLevel` I had refactored this and changed behaviour in
some cases. So this reverts the basic structure of the logic back to the
original, while leaving the hook in the new style.
Functions that implement expansion of response and config files depend
on many options, which are passes as arguments. Extending the expansion
requires new options, it in turn causes changing calls in various places
making them even more bulky.
This change introduces a class ExpansionContext, which represents set of
options that control the expansion. Its methods implements expansion of
responce files including config files. It makes extending the expansion
easier.
No functional changes.

The -fallow-half-arguments-and-returns option was removed in
59528e4bdb27ed4ab3, replaced with an always-on target option under
AArch64/Arm. There are two tests - fp16-sema.c and renderscripts.rs that
test that an error is produced for __fp16 function args/returns, which
are now expected to pass for Arm/AArch64. i.e they no longer give the
same error as before on native Arm/AArch64 machines. Alter the targets
of those tests to compensate.
