5017 number of function-like macro arguments from funlike_invocation_p,
5018 pass it to the new delete_macro_args to free the memory used by
5019 macro args. When -ftrack-macro-expansion is in effect, for macros
5020 that have no arguments, create a macro map for the macro expansion
5021 and use it to allocate proper virtual locations for tokens
5022 resulting from the expansion. Push an extended tokens context

5029 given macro. Handle the case of the argument of
5030 -ftrack-macro-expansion being < 2. Don't free macro arguments
5031 memory resulting from expand_arg here, as these are freed by the
5032 caller of replace_arg using delete_macro_args now. Push extended
5033 token context.
