    PR pch/53880
    * gengtype.c (struct walk_type_data): Add have_this_obj field.
    (walk_type): For functions that take a this_obj argument and
    that process fields with a GTY((length)) argument, write the
    test that write_types_local_process_field will write also at the
    head of the loop, effectively unswitching the loop.
    (write_func_for_structure, write_local_func_for_structure): Clear
    have_this_obj before calling walk_type.
    (write_local_func_for_structure): Set have_this_obj before walk_type.
    (write_array): Set have_this_obj for output of local pointer walking
    functions but not for marker functions.
    (write_types_local_process_field): Assert have_this_obj is set.

    * rtl.h (simplify_using_condition): Adjust prototype using bitmap
    from coretypes.h.
