This patch changes the default range used to anchor the include insertion to use
an expansion loc. This ensures that the location is valid, when the user relies
on the default range.
Driveby: extend a FIXME for a problem that was emphasized by this change; fix some spellings.

A number of declarations were leftover after the move from `clang::tooling` to
`clang::transformer`. This patch removes those declarations and upgrades the
handful of references to the deprecated declarations.
Differential Revision: https://reviews.llvm.org/D92340
This functionality is commonly needed in clang tidy checks (based on
transformer) that only print warnings, without suggesting any edits. The no-op
edit allows the user to associate a diagnostic message with a source location.

The new overloads apply directly to a node, like the
`clang::ast_matchers::match` functions, Rather than generating an
`EditGenerator` combinator.

This patch restores the default traversal for Transformer's `makeRule` to
`TK_AsIs`. The implicit mode has proven problematic.
Differential Revision: https://reviews.llvm.org/D87048
Currently, changes to includes are applied to an entire rule. However,
include changes may be specific to particular edits within a rule (for example,
they may apply to one file but not another). Also, include changes may need to
carry metadata, just like other changes. So, we make include changes first-class
edits.

This patch lifts `RootID` out of the `RewriteRule` class so that constructs
(e.g. inline functions) can that refer to the root id don't need to depend on
the `RewriteRule` class.
With this dependency, the patch is able to collect all `ASTEdit` helper function
declarations together with the class declaration, before the introduction of the
`RewriteRule` class. In the process, we also adjust some of the comments.
This patch is essentially a NFC.

The new combinator, `rewriteDescendants`, applies a rewrite rule to all
descendants of a specified bound node. That rewrite rule can refer to nodes
bound by the parent, both in the matcher and in the edits.

Summary:
This patch adds various combinators that help in constructing `EditGenerator`s:
* `noEdits`
* `ifBound`, specialized to `ASTEdit`
* `flatten` and `flattenVector` which allow for easy construction from a set
of sub edits.
* `shrinkTo`, which generates edits to shrink a given range to another that
it encloses.

`Metadata` is being changed from an `llvm::Any` to a `MatchConsumer<llvm::Any>`
so that it's evaluation can be be dependent on on `MatchResult`s passed in.

This change adds a Metadata field to ASTEdit, Edit, and AtomicChange so that
edits can have associated metadata and that metadata can be constructed with
Transformer-based RewriteRules. Metadata is ignored when applying edits to
source, but other consumers of AtomicChange can use this metadata to direct how
they want to consume each edit.

Summary:
`RewriteRule`'s `applyFirst` was brittle with respect to the default setting of the
`TraversalKind`. This patch builds awareness of traversal kinds directly into
rewrite rules so that they are insensitive to any changes in defaults.

Summary:
This revision simplifies the representation of edits in rewrite rules. The
simplified form is more general, allowing the user more flexibility in building
custom edit specifications.
The changes extend the API, without changing the signature of existing
functions. So this only risks breaking users that directly accessed the
`RewriteRule` struct.

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:
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: 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).
