At least in DECL_ABSTRACT_ORIGIN I saw us pointing to unlowered
templates that originally was used to produce the specialized node. If
the TEMPLATE_DECL is reached this way, perhaps we can just ignore
DECL_ABSTRACT_ORIGINs for time being as getting debug info right will be
interesting problem anyway?
However in general, Sadly in our types and initializers there are
language dependent nodes for sure, this is reason why analyze_expr
cgraph hook still exists (see cxx_callgraph_analyze_expr for some, I am
not sure if all of them are still alive, but they was about year ago
when I tried). We will need to lower those or make them part of Gimple.
