For g++.dg/debug/pr45660.C we have a limbo DIE for 'T' which has DECL_CONTEXT
of the type 'S'.  We create a DIE for 'S' when creating a DIE for the
FUNCTION_DECL 'i' which we do when we output that function (via
debug_hooks->function_decl) by emitting a DIE for its origin.  Same without
LTO, but with LTO we have dropped all non-FIELD_DECL members from 'S' so
we do not output the TYPE_DECL when we have a context for it - so it gets
on the limbo list.
