[PATCH] Move cpp_macro to cpplib.h

https://gcc.gnu.org/ml/gcc-patches/2018-08/msg01016.html
	libcpp/
	* cpp-id-data.h (uchar, UC): Move to internal.h
	(struct cpp_macro): Move to cpplib.h.
	* internal.h (uchar, UC): From cpp-id-data.h.
	* include/cpplib.h (struct cpp_macro): From cpp-id-data.h.
	gcc/c-family/
	* c-ada-spec.c: Don't #include "cpp-id-data.h"
	* c-cppbuiltin.c: Likewise.
	gcc/
	* cppbuiltin.c: Include "cpplib.h", not "cpp-id-data.h".
