* lto-cgraph.c (compute_ltrans_boundary): Add abstract origins into
boundaries.
* lto-streamer-out.c (tree_is_indexable): Results decls and
parm decls are not indexable.
(DFS_write_tree_body): Do not follow args and results.
(hash_tree): Likewise.
(output_functions): Rearrange so struct function is needed
only when real body is output; be able to also ouptut abstract
functions; output DECL_ARGUMENTS and DECL_RESULT.
(lto_output): When not in WPA, ale store abstract functions.
(write_symbol): Do not care about RESULT_DECL.
(output_symbol_p): Handle correctly sbtract decls.
* lto-streamer-in.c (input_function): Rearrange so struct
function can be NULL at entry; allow streaming of
functions w/o body; store DECL_ARGUMENTS and DECL_RESULT.
* ipa.c (symtab_remove_unreachable_nodes): Silence confused
sanity check during LTO.
* tree-streamer-out.c (write_ts_decl_non_common_tree_pointers): Skip
RESULT_DECl and DECL_ARGUMENTS.
* tree-streamer-in.c (lto_input_ts_decl_non_common_tree_pointers):
Likewise.
