Summary:
Added basic representation and parsing/sema handling of array-shaping
operations. Array shaping expression is an expression of form ([s0]..[sn])base,
where s0, ..., sn must be a positive integer, base - a pointer. This
expression is a kind of cast operation that converts pointer expression
into an array-like kind of expression.

https://reviews.llvm.org/D74564 enabled static building for libclang,
and for non CMake consumers they had to set the `CMAKE_EXPORTS` define
when consuming libclang.
This commit makes the non CMake users of the static building have to define `CMAKE_NO_EXPORTS`.

Force `-Werror=strict-prototypes` so that C API tests fail to compile if
we add a non-prototype declaration. This should help avoid regressions
like bddecba4b3 was fixing.

Added parsing/sema/codegen support for 'parallel master taskloop'
constructs. Some of the clauses, like 'grainsize', 'num_tasks', 'final'
and 'priority' are not supported in full, only constant expressions can
be used currently in these clauses.

This header is included by C code so the functions need to have a prototype. Also, fix the function definitions so that they have C linkage rather than C++ linkage.

This commit adds a new builtin, __builtin_bit_cast(T, v), which performs a
bit_cast from a value v to a type T. This expression can be evaluated at
compile time under specific circumstances.
The compile time evaluation currently doesn't support bit-fields, but I'm
planning on fixing this in a follow up (some of the logic for figuring this out
is in CodeGen). I'm also planning follow-ups for supporting some more esoteric
types that the constexpr evaluator supports, as well as extending
__builtin_memcpy constexpr evaluation to use the same infrastructure.

Depending on the included files and the used warning flags, e.g. -
Weverything, a huge number of warnings can be reported for included
files. As processing that many diagnostics comes with a performance
impact and not all clients are interested in those diagnostics, add a

In response to https://bugs.llvm.org/show_bug.cgi?id=33235, it became
clear that the current mechanism of hacking through checks for the
exception specification of a function gets confused really quickly when
there are alternate exception specifiers.
This patch introcues EST_NoThrow, which is the equivilent of
EST_noexcept when caused by EST_noThrow. The existing implementation is
left in place to cover functions with no FunctionProtoType.

D54996 Changed the behaviour of clang_Cursor_isAnonymous, but there is no alternative available to get the old behaviour in some cases, which is essential for determining if a record is syntactically accessible, e.g.
struct {
int x;
int y;
} foo;
struct {
struct {
int x;
int y;
};
} bar;
void fun(struct { int x; int y; } *param);
The only 'anonymous' struct here is the one nested in bar, since there is
no way to reference the struct itself, only the fields within. Though the
anonymity applies to the instance itself, not the type.
To avoid confusion, I have added a new function called clang_Cursor_isAnonymousRecordDecl
which has the old behaviour of clang_Cursor_isAnonymous (and updated the doc
for the latter as well, which was seemingly forgotten).

Summary:
This is useful because otherwise there's no easy way to distinguish #pragma
packed(N) from attribute(packed, aligned(N)) that isn't looking at field
offsets (since pragma packed() also creates a packed attribute).

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
The dir component ("somedir" in #include <somedir/fo...>) is considered fixed.
We append "foo" to each directory on the include path, and then list its files.
Completions are of the forms:
#include <somedir/fo^
foo.h>
fox/
The filter is set to the filename part ("fo"), so fuzzy matching can be
applied to the filename only.
No fancy scoring/priorities are set, and no information is added to
CodeCompleteResult to make smart scoring possible. Could be in future.
