This patch ensures we don't prematurely delete an abstract origin node, leading
to creating a new one after LIPO linking when we invoke similar handling in
symtab_remove_unreachable_nodes, which then does not have a resolved node. It
makes the handling of such nodes equivalent to that in
symtab_remove_unreachable_nodes.
Tested with regression tests and internal benchmarks. Ok for google/4_9
