gimplify.c (create_tmp_from_val): Remove is_formal parameter and set DECL_GIMPLE_REG_P unconditionally if appropriate.

2014-06-05  Richard Biener  <rguenther@suse.de>

	* gimplify.c (create_tmp_from_val): Remove is_formal parameter
	and set DECL_GIMPLE_REG_P unconditionally if appropriate.
	(lookup_tmp_var): Adjust.
	(prepare_gimple_addressable): Unset DECL_GIMPLE_REG_P here.
