4280 static functions.
4281 (cpp_get_token_1): New static function. Split and extended from
4282 cpp_get_token. Use reached_end_of_context and
4283 consume_next_token_from_context. Unify its return point. Move
4284 the location tweaking from cpp_get_token_with_location in here.
4285 (cpp_get_token): Use cpp_get_token_1
4286 (stringify_arg): Use the new arg_token_at.
4287 (paste_all_tokens): Support tokens coming from extended tokens
4288 contexts.
4289 (collect_args): Return the number of collected arguments, by
4290 parameter. Store virtual locations of tokens that constitute the
4291 collected args.
4292 (funlike_invocation_p): Return the number of collected arguments,
4293 by parameter.
4294 (enter_macro_context): Add a parameter for macro expansion point.
4295 Pass it to replace_args and to the "used" cpp callback. Get the
4296 number of function-like macro arguments from funlike_invocation_p,
4297 pass it to the new delete_macro_args to free the memory used by
4298 macro args. When -ftrack-macro-expansion is in effect, for macros
4299 that have no arguments, create a macro map for the macro expansion
4300 and use it to allocate proper virtual locations for tokens
4301 resulting from the expansion. Push an extended tokens context
4302 containing the tokens resulting from macro expansion and their
4303 virtual locations.
4304 (replace_args): Rename the different variables named 'count' into
4305 variables with more meaningful names. Create a macro map;
4306 allocate virtual locations of tokens resulting from this
4307 expansion. Use macro_arg_token_iter to iterate over tokens of a
4308 given macro. Handle the case of the argument of
4309 -ftrack-macro-expansion being < 2. Don't free macro arguments
4310 memory resulting from expand_arg here, as these are freed by the
4311 caller of replace_arg using delete_macro_args now. Push extended
4312 token context.
4313 (next_context, push_ptoken_context, _cpp_push_token_context)
4314 (_cpp_push_text_context): Properly initialize the context.
4315 (expand_arg): Use the new alloc_expanded_arg_mem,
4316 push_extended_tokens_context, cpp_get_token_1, and set_arg_token.
4317 (_cpp_pop_context): Really free the memory held by the context.
4318 Handle freeing memory used by extended tokens contexts.
4319 (cpp_get_token_with_location): Use cpp_get_token_1.

4321 (_cpp_backup_tokens): Support the new kinds of token contexts.
