Log:
	PR tree-optimization/31966
	PR tree-optimization/32533
	* tree-if-conv.c (add_to_dst_predicate_list): Use "edge", not
	"basic_block" description as its third argument.  Update function
	calls to get destination bb from "edge" argument.  Save "cond" into
	aux field of the edge.  Update prototype for changed arguments.
	(if_convertible_loop_p): Clear aux field of incoming edges if bb
	contains phi node.
	(find_phi_replacement_condition): Operate on incoming edges, not
	on predecessor blocks.  If there is a condition saved in the
	incoming edge aux field, AND it with incoming bb predicate.
	Return source bb of the first edge.
	(clean_predicate_lists): Clean aux field of outgoing node edges.
	(tree_if_conversion): Do not initialize cond variable. Move
	variable declaration into the loop.
	(replace_phi_with_cond_gimple_modify_stmt): Remove unneded
	initializations of new_stmt, arg0 and arg1 variables.
