TARGET_SUPPORTS_ALIASES.
2017-08-11 Martin Liska <mliska@suse.cz>
* asan.c (asan_protect_global): Replace ASM_OUTPUT_DEF with
TARGET_SUPPORTS_ALIASES.
* cgraph.c (cgraph_node::create_same_body_alias): Likewise.
* ipa-visibility.c (can_replace_by_local_alias): Likewise.
(optimize_weakref): Likewise.
* symtab.c (symtab_node::noninterposable_alias): Likewise.
* varpool.c (varpool_node::create_extra_name_alias): Likewise.
* defaults.h: Introduce TARGET_SUPPORTS_ALIASES.

* decl2.c (get_tls_init_fn): Replace ASM_OUTPUT_DEF with
TARGET_SUPPORTS_ALIASES.
(handle_tls_init): Likewise.
(note_mangling_alias): Likewise. Remove ATTRIBUTE_UNUSED for
both arguments.
* optimize.c (can_alias_cdtor): Likewise.
