Add a PragmaHandler Registry for plugins to add PragmaHandlers to This allows plugins which add AST passes to also define pragmas to do things like only enable certain behaviour of the AST pass in files where a certain pragma is used.

Make it possible for AST plugins to enable themselves by default Currently when an AST plugin is loaded it must then be enabled by passing -plugin pluginname or -add-plugin pluginname to the -cc1 command line. This patch adds a method to PluginASTAction which allows it to declare that the action happens before, instead of, or after the main AST action, plus the relevant changes to make the plugin action happen at that time automatically.
