[6/6] Preprocessor forced macro location 

https://gcc.gnu.org/ml/gcc-patches/2018-10/msg02044.html
	libcpp/
	* internal.h (struct cpp_reader): Rename forced_token_location_p
	to forced_token_location and drop its pointerness.
	* include/cpplib.h (cpp_force_token_locations): Take location, not
	pointer to one.
	* init.c (cpp_create_reader): Adjust.
	* lex.c (cpp_read_main_file): 

	gcc/c-family/
	* c-opts.c (c_finish_options): Adjust cpp_force_token_locations call.

	gcc/fortran/
	* cpp.c (gfc_cpp_init): Adjust cpp_force_token_locations call.
