* tree-ssa-sccvn.c (vn_nary_op_compute_hash): Also canonicalize
comparison operand order and commutative ternary op operand order.
(sccvn_dom_walker::cond_stack): New state to track temporary
expressions.
(sccvn_dom_walker::after_dom_children): Remove tempoary expressions
no longer valid.
(sccvn_dom_walker::record_cond): Add a single temporary conditional
expression.
(sccvn_dom_walker::record_conds): Add a temporary conditional
expressions and all related expressions also true/false.
(sccvn_dom_walker::before_dom_children): Record temporary
expressions based on the controlling condition of a single
predecessor. When trying to simplify a conditional statement
lookup expressions we might have inserted earlier.
