Summary:
This adds support for giving hints when using dynamic matchers with enum args. Take this query, I couldn't figure out why the matcher wasn't working:
(Turns out it needed to be "IntegralToBoolean", but thats another bug itself)
```
clang-query> match implicitCastExpr(hasCastKind("CK_IntegralToBoolean"))
1:1: Error parsing argument 1 for matcher implicitCastExpr.
1:18: Error building matcher hasCastKind.
1:30: Incorrect type for arg 1. (Expected = string) != (Actual = String)
```
With this patch the new behaviour looks like this:
```
clang-query> match implicitCastExpr(hasCastKind("CK_IntegralToBoolean"))
1:1: Error parsing argument 1 for matcher implicitCastExpr.
1:18: Error building matcher hasCastKind.
1:30: Unknown value 'CK_IntegralToBoolean' for arg 1; did you mean 'IntegralToBoolean'
```
There are no test cases for this yet as there simply isn't any infrastructure for testing errors reported when parsing args that I can see.

Move the listing of allowed clauses per OpenMP directive to the new
macro file in `llvm/Frontend/OpenMP`. Also, use a single generic macro
that specifies the directive and one allowed clause explicitly instead
of a dedicated macro per directive.
We save 800 loc and boilerplate for all new directives/clauses with no
functional change. We also need to include the macro file only once and
not once per directive.
Depends on D77112.

This is a cleanup and normalization patch that also enables reuse with
Flang later on. A follow up will clean up and move the directive ->

DynTypedNode and ASTNodeKind are implemented as part of the clang AST
library, which uses the main clang namespace. There doesn't seem to be a
need for this extra level of namespacing.
I left behind aliases in the ast_type_traits namespace for out of tree
clients of these APIs. To provide aliases for the enumerators, I used
this pattern:
namespace ast_type_traits {
constexpr TraversalKind TK_AsIs = ::clang::TK_AsIs;
}
I think the typedefs will be useful for migration, but we might be able
to drop these enumerator aliases.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary:
The analysis for const-ness of local variables required a view generally useful
matchers that are extracted into its own patch.
They are `decompositionDecl` and `forEachArgumentWithParamType`, that works
for calls through function pointers as well.

This matcher matches any node and at the same time executes all its
inner matchers to produce any possbile result bindings.
This is useful when a user wants certain supplementary information
that's not always present along with the main match result.
Adds a new ASTMatcher condition called 'hasInitStatement()' that matches if,
switch and range-for statements with an initializer. Reworked clang-tidy
readability-else-after-return to handle variables in the if condition or init
statements in c++17 ifs. Also checks if removing the else would affect object
lifetimes in the else branch.
Fixes PR44364.
Revert "Fix -Wunused-lambda-capture warnings."
This reverts commit 2369560f4a.
This reverts commit 522ee29a4f.
clang/lib/ASTMatchers/Dynamic/Parser.cpp:610:13: warning: implicit conversion turns string literal into bool: 'const char [35]' to 'bool' [-Wstring-conversion]
assert(!"Newline should never be found here");
Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

Summary:
This allows ASTs to be merged when they contain ChooseExpr (the GNU
__builtin_choose_expr construction). This is needed, for example, for
cross-CTU analysis of C code that makes use of __builtin_choose_expr.
The node is already supported in the AST, but it didn't have a matcher
in ASTMatchers. So, this change adds the matcher and adds support to
ASTImporter.
This was originally reviewed and approved in
https://reviews.llvm.org/D58292 and submitted as r354832. It was
reverted in r354839 due to failures on the Windows CI builds.
This version fixes the test failures on Windows, which were caused by
differences in template expansion between versions of clang on different
OSes. The version of clang built with MSVC and running on Windows never
expands the template in the C++ test in ImportExpr.ImportChooseExpr in
clang/unittests/AST/ASTImporter.cpp, but the version on Linux does for
the empty arguments and -fms-compatibility.
So, this version of the patch drops the C++ test for
__builtin_choose_expr, since that version was written to catch
regressions of the logic for isConditionTrue() in the AST import code
for ChooseExpr, and those regressions are also caught by
ASTImporterOptionSpecificTestBase.ImportChooseExpr, which does work on
Windows.

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 crux of the issue that is being fixed is that lookup could not find
previous decls of a friend class. The solution involves making the
friend declarations visible in their decl context (i.e. adding them to
the lookup table).
Also, we simplify `VisitRecordDecl` greatly.
This fix involves two other repairs (without these the unittests fail):
(1) We could not handle the addition of injected class types properly
when a redecl chain was involved, now this is fixed.
(2) DeclContext::removeDecl failed if the lookup table in Vector form
did not contain the to be removed element. This caused troubles in
ASTImporter::ImportDeclContext. This is also fixed.
