This reverts commit 97aa593a83 as it
causes problems (PR45453) https://reviews.llvm.org/D77574#1966321.
This additionally adds an explicit reference to FrontendOpenMP to
clang-tidy where ASTMatchers is used.
This is hopefully just a temporary solution. The dependence on
`FrontendOpenMP` from `ASTMatchers` should be handled by CMake
implicitly, not us explicitly.

Summary:
ASTMatchers is used in various places and it now exposes the
LLVMFrontendOpenMP library to its users without them needing to depend
on it explicitly.

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.

Summary:
Second attempt -- the first was reverted in commit 0e480b39c6, because of test breakages. This revision fixes the cause of the test breakages.
Original description follows:
This patch adds `getAssociatedRange` which, for a given decl, computes preceding
and trailing text that would conceptually be associated with the decl by the
reader. This includes comments, whitespace, and separators like ';'.

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: Currently, an attempt to rewrite source code inside a macro expansion succeeds, but results in empty text, rather than failing with an error. This patch restructures to the code to explicitly validate ranges before attempting to edit them.

Summary:
Adds combinators `maybeDeref` and `maybeAddressOf` to provide a uniform way to handle
nodes which may be bound to either a pointer or a value (most often in the
context of member expressions). Such polymorphism is already supported by
`access`; these combinators extend it to more general uses.

Summary:
This revision introduces a new interface `MatchComputation` which generalizes
the `Stencil` interface and replaces the `std::function` interface of
`MatchConsumer`. With this revision, `Stencil` (as an abstraction) becomes just
one collection of implementations of
`MatchComputation<std::string>`. Correspondingly, we remove the `Stencil` class
entirely in favor of a simple type alias, deprecate `MatchConsumer` and change
all functions that accepted `MatchConsumer<std::string>` to use
`MatchComputation<std::string>` instead.

Summary:
Currently, stencils are defined as a sequence of `StencilParts`. This
differentiation adds an unneeded layer of complexity to the definition of
Stencils. This change significantly simplifies the type structure: a stencil is
now conceptually any object implementing `StencilInterface` and `Stencil` is
just a thin wrapper for pointers to this interface.
To account for the sequencing that was supported by the old `Stencil` type, we
introduce a sequencing class that implements `StencilInterface`. That is,
sequences are just another kind of Stencil and no longer have any special
status.
Corresponding to this change in the type structure, we change the way `cat` is
used (and defined). `cat` bundles multiple features: it builds a stencil from a
sequence of subcomponents and admits multiple different types for its arguments,
while coercing them into the right type. Previously, `cat` was also used to
coerce a single `StencilPart` into a `Stencil`. With that distinction gone, many
uses of `cat` (e.g. in the tests) are unnecessary and have, therefore, been
removed.

Summary: Move the `RewriteRule` class and related declarations into its own set
of files (header, implementation). Only the `Transformer` class is left in the
Transformer-named files. This change clarifies the distinction between the
`RewriteRule` class, which is essential to the Transformer library, and the
`Transformer` class, which is only one possible `RewriteRule` interpreter
(compare to `TransformerClangTidyCheck`, a clang-tidy based interpreter).

Summary:
Removes the `isEqual` method from StencilPartInterface and modifies equality to
use the string representation returned by the `toString` method for comparison.
This means the `run` and `selection` stencils return true by default, and
clients should be cautious in relying on equality operator for comparison of
stencils containing parts generated by these functions.
It also means we no longer need the custom RTTI support (typeId() and
down_cast()), so it has been removed.

Summary:
The Transformer library has been growing inside of
lib/Tooling/Refactoring. However, it's not really related to anything else in
that directory. This revision moves all Transformer-related files into their own
include & lib directories. A followup revision will (temporarily) add
forwarding headers to help any users migrate their code to the new location.
