Summary:
Acts on `BinaryOperator` and `UnaryOperator` and functions the same as `anyOf(hasOperatorName(...), hasOperatorName(...), ...)`
Documentation generation isn't perfect but I feel that the python doc script needs updating for that

Summary:
This revision adds matchers that match calls to the gtest EXPECT and ASSERT
macros almost like function calls. The matchers are placed in separate files
(GtestMatchers...), because they are specific to the gtest library.

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.

Summary:

statement is (transitively) expanded from a given macro.

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.
Children of InitListExpr are traversed twice by RAV, so this code
populates a vector to represent the possibly-multiple parents (in
reality in this situation the parent is the same and is therefore
de-duplicated).
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.
Summary:
These overloads make it possible to wrap unless(), anyOf(), has() etc
with the traverse matcher.

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");
Summary:
This will eventually allow traversal of an AST while ignoring invisible
AST nodes. Currently it depends on the available enum values for
TraversalKinds. That can be extended to ignore all invisible nodes in
the future.

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 change updates `isDerivedFrom` to support Objective-C classes by
converting it to a polymorphic matcher.
Notes:
The matching behavior for Objective-C classes is modeled to match the
behavior of `isDerivedFrom` with C++ classes. To that effect,
`isDerivedFrom` matches aliased types of derived Objective-C classes,
including compatibility aliases. To achieve this, the AST visitor has
been updated to map compatibility aliases to their underlying
Objective-C class.
`isSameOrDerivedFrom` also provides similar behaviors for C++ and
Objective-C classes. The behavior that
`cxxRecordDecl(isSameOrDerivedFrom("X"))` does not match
`class Y {}; typedef Y X;` is mirrored for Objective-C in that
`objcInterfaceDecl(isSameOrDerivedFrom("X"))` does not match either
`@interface Y @end typedef Y X;` or
`@interface Y @end @compatibility_alias X Y;`.
Test Notes:
Ran clang unit tests.
