trans.c (gnat_to_gnu): Deal with a missing library unit instead of calling gnat_to_gnu on Emtpy.

* gcc-interface/trans.c (gnat_to_gnu) <N_Subprogram_Body_Stub>: Deal
	with a missing library unit instead of calling gnat_to_gnu on Emtpy.
	Remove last bits of support for SCIL nodes.  Add cases for nodes that
	should only be present when annotating types.  Add default abort.
