* tree-if-conv.c (set_bb_predicate): Assert we only set
canonical predicates.
(add_to_predicate_list): Simplify. Allow TRUTH_NOT_EXPR
around canonical predicates.
(predicate_bbs): Do not re-gimplify already canonical
predicates. Properly unshare them though.
(find_phi_replacement_condition): Simplify.
