cgraph.c (cgraph_release_function_body): Use used_as_abstract_origin.
* cgraph.c (cgraph_release_function_body): Use used_as_abstract_origin.
(cgraph_release_function_body): Likewise.
(cgraph_can_remove_if_no_direct_calls_p): Likewise.
* cgraph.h (cgrpah_node): Rename abstract_and_needed
to used_as_abstract_origin.
* tree-inline-transfrom.c (can_remove_node_now_p_1): Do not remove
symbols used as abstract origins.
* cgraphunit.c (analyze_functions): Update.
* ipa.c (symtab_remove_unreachable_nodes): Recompute used_as_abstract_origin.
* tree-inline.c (tree_function_versioning): Update
used_as_abstract_origin; be ready for DECL_RESULT and DECL_ARGUMENTS to be
NULL.
