* internal.h (cpp_reader::top_most_macro_node): New data member.
* macro.c (enter_macro_context): Pass the location of the end of
the top-most invocation of the function-like macro, or the
location of the expansion point of the top-most object-like macro.
(cpp_get_token_1): Store the top-most macro node in the new
pfile->top_most_macro_node data member.
* gcc.dg/cpp/builtin-macro-1.c: New test case.
