Right now we can only add a single warning, notes are not possible.
Apparently some provisions were made to allow notes, but they were never
propagated all the way to the diagnostics.

Given that we provide an EditGenerator edit(ASTEdit), we can't ever be
sure that the user won't give us an empty replacement.

Messages generated by Transformer rules may have `%` in them, which
needs to be escaped before being passed to `diag`, which interprets them
specially (and crashes if they are misused).
Differential Revision: https://reviews.llvm.org/D124952
Change RewriteRule from holding an `Explanation` to being able to generate
arbitrary metadata. Where TransformerClangTidyCheck was interested in a string
description for the diagnostic, other tools may be interested in richer metadata
at a higher level of abstraction than at the edit level (which is currently
available as ASTEdit::Metadata).

Fixes bug http://bugs.llvm.org/show_bug.cgi?id=49000.
This patch allows Clang-Tidy checks to do
diag(X->getLocation(), "text") << Y->getSourceRange();
and get the highlight of `Y` as expected:
warning: text [blah-blah]
xxx(something)

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
Currently, `node` only includes the semicolon for (some) statements. However,
declarations have the same issue of (potentially) trailing semicolons, so `node`
should behave the same for them.

Summary:
The new option allows the user to specify which file naming convention is used
by the source code ('llvm' or 'google').

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:
Updates the relevant source files to use bindings in `clang::transformer` rather
than `clang::tooling`.

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.

One call `makeRule` is unqualified (and unintentionally relying on ADL to
resolve correctly). This revision qualifies that call for consistency and to
drop use of ADL.

Summary:
This patch changes the location specified to the
`ClangTidyCheck::diag()`. Currently, the beginning of the matched range is
used. This patch uses the beginning of the first fix's range. This change both
simplifies the code and (hopefully) gives a more intuitive result: the reported
location aligns with the fix(es) provided, rather than the (arbitrary) range of
the rule's match.
N.B. this patch will break the line offset numbers in lit tests if the first fix
is not at the beginning of the match.

Summary:
This revision implements support for the `AddedIncludes` field in
RewriteRule cases; that is, it supports specifying the addition of include
directives in files modified by the clang tidy check.

Summary: Tidy check behavior often depends on language and/or clang-tidy options. This revision allows a user of TranformerClangTidyCheck to pass rule _generator_ in place of a rule, where the generator takes both the language and clang-tidy options. Additionally, the generator returns an `Optional` to allow for the case where the check is deemed irrelevant/disable based on those options.

Summary:
In general, the `Explanation` field is optional in `RewriteRule` cases. But,
because the primary purpose of clang-tidy checks is to provide users with
diagnostics, we assume that a missing explanation is a bug. This change adds an
assertion that checks all cases for an explanation, and updates the code to rely
on that assertion correspondingly.

This revision introduces an adaptor from Transformer's rewrite rules
(`clang::tooling::RewriteRule`) to `ClangTidyCheck`. For example, given a
RewriteRule `MyCheckAsRewriteRule`, it lets one define a tidy check as follows:
```
class MyTidyCheck : public TransformerClangTidyCheck {
public:
MyTidyCheck(StringRef Name, ClangTidyContext *Context)
: TransformerClangTidyCheck(MyCheckAsRewriteRule, Name, Context) {}
};
```
