Reduced testcase.

Adding a reduced testcase for this bug. 

Honza: To answer your question, if I add gcc_assert (origin_node) before the
dereference, it triggers - so in my case we definitely do have a NULL
origin_node.

If I dump decl, DECL_ABSTRACT_ORIGIN (decl) the results look "sane" (I
think)...

decl:

    full-name "std::scoped_allocator_adaptor<_OuterAlloc,
_InnerAllocs>::scoped_allocator_adaptor() [with _OuterAlloc =
std::allocator<short int>; _InnerAllocs = {}]"
    pending-inline-info 0x7f32a2507ab0 template-info 0x7f32a2362680

DECL_ABSTRACT_ORIGIN:

    full-name "std::scoped_allocator_adaptor<_OuterAlloc,
_InnerAllocs>::scoped_allocator_adaptor() [with _OuterAlloc =
std::allocator<short int>; _InnerAllocs = {}]"
    pending-inline-info 0x7f32a2507990 template-info 0x7f32a2362680

cgraph_get_node (DECL_ABSTRACT_ORIGIN (decl)) == (nil)
