Save some memory at debug stream-in time
This allows us to release references to BLOCKs by not keeping
them rooted in the external_die_map but instead remove it from
there as soon as we created the corresponding stub DIE. For
decls it doesn't help since we still keep the decl_die_table.

* dwarf2out.c (maybe_create_die_with_external_ref): Remove
hashtable entry.
