tree-if-conv.c (if_convertible_gimple_assign_stmt_p): Use ifcvt_could_trap_p also when not flag_tree_loop_if_convert_stores. 

2015-07-10  Richard Biener  <rguenther@suse.de>

	* tree-if-conv.c (if_convertible_gimple_assign_stmt_p):
	Use ifcvt_could_trap_p also when not flag_tree_loop_if_convert_stores.
	(if_convertible_loop_p_1): For this always compute bb predicates.
	(if_convertible_loop_p): And free them.
