Pirama Arumuga Nainar 0fd0a010a1 [git-clang-format] Do not apply clang-format to symlinks
This fixes PR46992.

Git stores symlinks as text files and we should not format them even if
they have one of the requested extensions.

(Move the call to `cd_to_toplevel()` up a few lines so we can also print
the skipped symlinks during verbose output.)

Anastasia Stulova e994e74bca [OpenCL] Add clang extension for non-portable kernel parameters.
Added __cl_clang_non_portable_kernel_param_types extension that
allows using non-portable types as kernel parameters. This allows
bypassing the portability guarantees from the restrictions specified
in C++ for OpenCL v1.0 s2.4.

Currently this only disables the restrictions related to the data
layout. The programmer should ensure the compiler generates the same
layout for host and device or otherwise the argument should only be
accessed on the device side. This extension could be extended to other
case (e.g. permitting size_t) if desired in the future.

Dan Liew 2d42b2ee7b [ASan] Rename `-fsanitize-address-destructor-kind=` to drop the `-kind` suffix.
Renaming the option is based on discussions in https://reviews.llvm.org/D101122.

It is normally not a good idea to rename driver flags but this flag is
new enough and obscure enough that it is very unlikely to have adopters.

While we're here also drop the `<kind>` metavar. It's not necessary and
is actually inconsistent with the documentation in
`clang/docs/ClangCommandLineReference.rst`.

Marek Kurdej 9363aa90bf [clang-format] Add `SpacesInAngles: Leave` option to keep spacing inside angle brackets as is.
A need for such an option came up in a few libc++ reviews. That's because libc++ has both code in C++03 and newer standards.
Currently, it uses `Standard: C++03` setting for clang-format, but this breaks e.g. u8"string" literals.
Also, angle brackets are the only place where C++03-specific formatting needs to be applied.

Joshua Haberman 8344675908 Implemented [[clang::musttail]] attribute for guaranteed tail calls.
This is a Clang-only change and depends on the existing "musttail"
support already implemented in LLVM.

The [[clang::musttail]] attribute goes on a return statement, not
a function definition. There are several constraints that the user
must follow when using [[clang::musttail]], and these constraints
are verified by Sema.

Tail calls are supported on regular function calls, calls through a
function pointer, member function calls, and even pointer to member.

Future work would be to throw a warning if a users tries to pass
a pointer or reference to a local variable through a musttail call.

Max Sagebaum dda978eef8 [clang-format] Option for empty lines after an access modifier.
The current logic for access modifiers in classes ignores the option 'MaxEmptyLinesToKeep=1'. It is therefore impossible to have a coding style that requests one empty line after an access modifier. The patch allows the user to configure how many empty lines clang-format should add after an access modifier. This will remove lines if there are to many and will add them if there are missing.

Aaron Ballman 4be8a26951 Use tablegen to diagnose mutually exclusive attributes
Currently, when one or more attributes are mutually exclusive, the
developer adding the attribute has to manually emit diagnostics. In
practice, this is highly error prone, especially for declaration
attributes, because such checking is not trivial. Redeclarations
require you to write a "merge" function to diagnose mutually exclusive
attributes and most attributes get this wrong.

This patch introduces a table-generated way to specify that a group of
two or more attributes are mutually exclusive:

def : MutualExclusions<[Attr1, Attr2, Attr3]>;

This works for both statement and declaration attributes (but not type
attributes) and the checking is done either from the common attribute
diagnostic checking code or from within mergeDeclAttribute() when
merging redeclarations.

Warn when a function pointer is cast to an incompatible function
pointer. In a cast involving function types with a variable argument
list only the types of initial arguments that are provided are
considered. Any parameter of pointer-type matches any other
pointer-type. Any benign differences in integral types are ignored, like
int vs. long on ILP32 targets. Likewise type qualifiers are ignored. The
function type void (*) (void) is special and matches everything, which
can be used to suppress this warning. In a cast involving pointer to
member types this warning warns whenever the type cast is changing the
pointer to member type. This warning is enabled by -Wextra.
