(FOR_EACH_ALIAS): New macro iterates all direct aliases for a node.
* cgraph.c (cgraph_for_node_thunks_and_aliases): Usage of
FOR_EACH_ALIAS added.
(cgraph_for_node_and_aliases): Likewise.
* cgraphunit.c (assemble_thunks_and_aliases): Likewise.
* ipa-inline.c (reset_edge_caches): Likewise.
(update_caller_keys): Likewise.
* trans-mem.c (ipa_tm_execute): Likewise.
*varpool.c (varpool_analyze_node): Likewise.
(varpool_for_node_and_aliases): Likewise.
* ipa-ref.h (first_alias): New function.
(last_alias): Likewise.
(has_aliases_p): Likewise.
* ipa-ref.c (ipa_ref::remove_reference): Removal function
is sensitive to IPA_REF_ALIASes.
* symtab.c (symtab_node::add_reference): Node of IPA_REF_ALIAS type
are put at the beginning of the list.
(symtab_node::iterate_direct_aliases): New function.
* lto-partition.c (add_symbol_to_partition_1): Usage of
FOR_EACH_ALIAS added.
