5233 static functions.
5234 (cpp_get_token_1): New static function. Split and extended from
5235 cpp_get_token. Use reached_end_of_context and
5236 consume_next_token_from_context. Unify its return point. Move
5237 the location tweaking from cpp_get_token_with_location in here.
5238 (cpp_get_token): Use cpp_get_token_1
5239 (stringify_arg): Use the new arg_token_at.
5240 (paste_all_tokens): Support tokens coming from extended tokens
5241 contexts.
5242 (collect_args): Return the number of collected arguments, by
5243 parameter. Store virtual locations of tokens that constitute the
5244 collected args.
5245 (funlike_invocation_p): Return the number of collected arguments,
5246 by parameter.
5247 (enter_macro_context): Add a parameter for macro expansion point.
5248 Pass it to replace_args and to the "used" cpp callback. Get the
5249 number of function-like macro arguments from funlike_invocation_p,
5250 pass it to the new delete_macro_args to free the memory used by
5251 macro args. When -ftrack-macro-expansion is in effect, for macros
5252 that have no arguments, create a macro map for the macro expansion
5253 and use it to allocate proper virtual locations for tokens
5254 resulting from the expansion. Push an extended tokens context
5255 containing the tokens resulting from macro expansion and their
5256 virtual locations.
5257 (replace_args): Rename the different variables named 'count' into
5258 variables with more meaningful names. Create a macro map;
5259 allocate virtual locations of tokens resulting from this
5260 expansion. Use macro_arg_token_iter to iterate over tokens of a
5261 given macro. Handle the case of the argument of
5262 -ftrack-macro-expansion being < 2. Don't free macro arguments
5263 memory resulting from expand_arg here, as these are freed by the
5264 caller of replace_arg using delete_macro_args now. Push extended
5265 token context.
5266 (next_context, push_ptoken_context, _cpp_push_token_context)
5267 (_cpp_push_text_context): Properly initialize the context.
5268 (expand_arg): Use the new alloc_expanded_arg_mem,
5269 push_extended_tokens_context, cpp_get_token_1, and set_arg_token.
5270 (_cpp_pop_context): Really free the memory held by the context.
5271 Handle freeing memory used by extended tokens contexts.
5272 (cpp_get_token_with_location): Use cpp_get_token_1.

5274 (_cpp_backup_tokens): Support the new kinds of token contexts.
