re PR middle-end/56461 (GCC is leaking lots of memory)
PR middle-end/56461
* internal.h (struct cpp_buffer): Add to_free field.
(_cpp_pop_file_buffer): Add third argument.
* files.c (_cpp_stack_file): Set buffer->to_free.
(_cpp_pop_file_buffer): Add to_free argument. Free to_free
if non-NULL, and if equal to file->buffer_start, also clear
file->buffer{,_start,_valid}.
* directives.c (_cpp_pop_buffer): Pass buffer->to_free
to _cpp_pop_file_buffer.
