We need to eagerly instantiate constexpr functions used in them even if
the default argument is never actually used, because we might evaluate
portions of it when performing semantic checks.

Summary:
This patch adds a test for requires with unified share memory clause when a declare target link is present.
This test needs to go in prior to changes to declare target link for comparison purposes.

Summary:
We put only part of the signature starting with a function name into "typed text"
chunks now, previously the whole signature was "typed text".
This leads to meaningful fuzzy match scores, giving better signals to
compare with other completion items.
Ideally, we would not display the result type to the user, but that requires adding
a new kind of completion chunk.

If the source file path contains directory junctions, and we resolve them when
printing diagnostic messages, these paths look independent for an IDE.
For example, both Visual Studio and Visual Studio Code open separate editors
for such paths, which is not only inconvenient but might even result in losing
changes made in one of them.

Previously, the only way to display the list of available checkers was
to invoke the analyzer with -analyzer-checker-help frontend flag. This
however wasn't really great from a maintainer standpoint: users came
across checkers meant strictly for development purposes that weren't to
be tinkered with, or those that were still in development. This patch
creates a clearer division in between these categories.
From now on, we'll have 3 flags to display the list checkers. These
lists are mutually exclusive and can be used in any combination (for
example to display both stable and alpha checkers).
-analyzer-checker-help: Displays the list for stable, production ready
checkers.
-analyzer-checker-help-alpha: Displays the list for in development
checkers. Enabling is discouraged
for non-development purposes.
-analyzer-checker-help-developer: Modeling and debug checkers. Modeling
checkers shouldn't be enabled/disabled
by hand, and debug checkers shouldn't
be touched by users.

New -cc1 arguments, such as -faddrsig, have started appearing after the

OptTable treats arguments starting with / that aren't a known option
as filenames. This means lld-link's and clang-cl's typo correction for
unknown flags didn't do spell checking for misspelled options that start
with /.
I first tried changing OptTable, but that got pretty messy, see PR41787
comments 2 and 3.
Instead, let lld-link's and clang's (including clang-cl's) "file not
found" diagnostic check if a non-existent file looks like it could be a
mis-spelled option, and if so add a "did you mean" suggestion to the
"file not found" diagnostic.
While here, make formatting of a few diagnostics a bit more
self-consistent.
Fixes PR41787.

r355317 changed builtins/allocation functions to use the default calling
convention in order to support platforms that use non-cdecl calling
conventions by default.
However the default calling convention is overridable on Windows 32 bit
implementations with some of the /G options. The intent is to permit the
user to set the calling convention of normal functions, however it
should NOT apply to builtins and C++ allocation functions.
This patch ensures that the builtin/allocation functions always use the
Target specific Calling Convention, ignoring the user overridden version
of said default.

This change is a consequence of the discussion in "RFC: Place libs in
Clang-dedicated directories", specifically the suggestion that
libunwind, libc++abi and libc++ shouldn't be using Clang resource
directory. Tools like clangd make this assumption, but this is
currently not true for the LLVM_ENABLE_PER_TARGET_RUNTIME_DIR build.
This change addresses that by moving the output of these libraries to
lib/$target/c++ and include/c++ directories, leaving resource directory
only for compiler-rt runtimes and Clang builtin headers.

Before e97b5f5cf3 ([clang][Darwin] Refactor header search path logic
into the driver), both --sysroot and -isysroot worked to specify where
to look for system and C++ headers on Darwin. However, that change
caused clang to start ignoring --sysroot.
This fixes the regression, and adds tests.
(I also note that on all other platforms, clang seems to almost
completely ignore -isysroot, but that's another issue...)

Found in a bootstrap of LLVM with implicit modules, resulting in a
deadlock of some Orc unit tests with libstdc++ 8.1. An enum was used as
part of the implementation of std::recursive_mutex and this bug resulted
in the constant initialization of zero instead of the desired non-zero
value. => Badness.
Richard Smith tells me neither of these fields are necessarily canonical
& so using declaresSamEntity is the right solution here (rather than
changing both of these Fields to be canonical by construction/from their
source)

Overaligned and underaligned types (i.e. types where the alignment has been
increased or decreased using the aligned and packed attributes) weren't being
correctly handled in all cases, as the unadjusted alignment should be used.
This patch also adjusts getTypeUnadjustedAlign to correctly handle typedefs of
non-aggregate types, which it appears it never had to handle before.

Summary:
Values returned by GCCInstallation.getParentLibPath() and
GCCInstallation.getTriple() are not valid unless
GCCInstallation.isValid() returns true. This has previously been
ignored, and the former two values were used without checking whether
GCCInstallation is valid. This led to the bad path "/../bin" being added
to the list of program paths.

Summary:
This patch adds support for the registration of the requires directives with the runtime.
Each requires directive clause will enable a particular flag to be set.
The set of flags is passed to the runtime to be checked for compatibility with other such flags coming from other object files.
The registration function is called whenever OpenMP is present even if a requires directive is not present. This helps detect cases in which requires directives are used inconsistently.
