[dwarf] get_debug_type of qualified_type
When we choose the narrower/packed variant of a type as the main debug
info type, we fail to output its name if we fail to follow
debug type for the TYPE_NAME decl type in modified_type_die.
for gcc/ChangeLog
* dwarf2out.cc (modified_type_die): Follow name's debug type.
