[OpenACC] Extract 'pass_oacc_loop_designation' out of 'pass_oacc_device_lower'

This really is a separate step -- and another pass to be added between the two,
later on.

	gcc/
	* omp-offload.c (oacc_loop_xform_head_tail, oacc_loop_process):
	'update_stmt' after modification.
	(pass_oacc_loop_designation): New function, extracted out of...
	(pass_oacc_device_lower): ... this.
	(pass_data_oacc_loop_designation, pass_oacc_loop_designation)
	(make_pass_oacc_loop_designation): New
	* passes.def: Add it.
	* tree-parloops.c (create_parallel_loop): Adjust.
	* tree-pass.h (make_pass_oacc_loop_designation): New.
	gcc/testsuite/
