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 TransformerTidy {
   public:
    MyTidyCheck(StringRef Name, ClangTidyContext *Context)
        : TransformerTidy(MyCheckAsRewriteRule, Name, Context) {}
  };
