re PR tree-optimization/50735 (gcc.dg/torture/vector-2.c:52:1: ICE: verify_ssa failed at -O1 and above)
PR tree-optimization/50735 * function.c (gimplify_parameters): Use create_tmp_var instead of create_tmp_reg. If parm is not TREE_ADDRESSABLE and type is complex or vector type, set DECL_GIMPLE_REG_P. From-SVN: r180154
