Summary:
In ASTMatcher, when we have `has(...)` and `hasParent(...)` called with the same internal matcher on the same node, the memoization process will mix-up the two calls because the direction of the traversal is not part of the memoization key.
This patch adds this information.

Summary:
The unittest for AST matchers has its own way to specify language
standards. I unified it with the shared infrastructure from

Summary: Adds a matcher called `hasOperands` for `BinaryOperator`'s when you need to match both sides but the order isn't important, usually on commutative operators.

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.
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.

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

of (hopefully) all the llvm::make_unique instances across the monorepo.

Certain combinations of gcc and ccache fail when the raw

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.

Compound literals, enums, file-scoped arrays, etc. require their
