PR 63300/debug
* tree.c (check_base_type): New.
(check_qualified_type): Exploit new helper function above.
* tree.h (check_base_type): New prototype.
* dwarf2out.c (get_nearest_type_subqualifiers): New.
(modified_type_die): Fix handling for qualifiers. Qualifiers to
"peel off" are now determined using get_nearest_type_subqualifiers.
