re PR debug/45997 (__unknown__ type name for typedef'd int)
PR debug/45997
* dwarf2out.c (modified_type_die): If both is_const_type and
is_volatile_type is set, start with DW_TAG_const_type or
DW_TAG_volatile_type depending on where we get qualified type
in the recursive call.
* g++.dg/debug/dwarf2/pr45997-1.C: New test.
* g++.dg/debug/dwarf2/pr45997-2.C: New test.
