528 (cpp_get_token_1): New static function. Split and extended from
529 cpp_get_token. Use reached_end_of_context and

531 the location tweaking from cpp_get_token_with_location in here.

545 macro args. When -ftrack-macro-expansion is in effect, for macros
546 that have no arguments, create a macro map for the macro expansion
547 and use it to allocate proper virtual locations for tokens
548 resulting from the expansion. Push an extended tokens context

556 -ftrack-macro-expansion being < 2. Don't free macro arguments
