4980 by parameter.
4981 (enter_macro_context): Add a parameter for macro expansion point.
4982 Pass it to replace_args and to the "used" cpp callback. Get the
4983 number of function-like macro arguments from funlike_invocation_p,
4984 pass it to the new delete_macro_args to free the memory used by
4985 macro args. When -ftrack-macro-expansion is in effect, for macros
4986 that have no arguments, create a macro map for the macro expansion
4987 and use it to allocate proper virtual locations for tokens
4988 resulting from the expansion. Push an extended tokens context
4989 containing the tokens resulting from macro expansion and their
4990 virtual locations.
4991 (replace_args): Rename the different variables named 'count' into
4992 variables with more meaningful names. Create a macro map;
4993 allocate virtual locations of tokens resulting from this
4994 expansion. Use macro_arg_token_iter to iterate over tokens of a
4995 given macro. Handle the case of the argument of
4996 -ftrack-macro-expansion being < 2. Don't free macro arguments
4997 memory resulting from expand_arg here, as these are freed by the
4998 caller of replace_arg using delete_macro_args now. Push extended
4999 token context.
5000 (next_context, push_ptoken_context, _cpp_push_token_context)
5001 (_cpp_push_text_context): Properly initialize the context.
5002 (expand_arg): Use the new alloc_expanded_arg_mem,
