cgraph.c: Include lto-streamer.h
* cgraph.c: Include lto-streamer.h
(change_decl_assembler_name): Work when assembler name hash is at place.
(cgraph_make_decl_local): When localizing COMDAT symbol at WPA stage, be
sure to rename it to avoid name clash.
* ipa.c (cgraph_externally_visible_p, function_and_variable_visibility):
Localize hidden symbols only when locally defined.
