[Bug lto/44950] dwarf2out ICE with WHOPR build of mozilla

[rguenth at gcc dot gnu dot org]

Without LTO the limbo DIE has a non-NULL get_AT_ref (die,
DW_AT_abstract_origin),
a DW_TAG_subprogram.  For some reason that doesn't get created with LTO
(not easy to follow why).

More reduced testcase:

struct Base { ~Base (); };
void fun(void) { struct Deriv : Base { } x; }
