mn10300: Fixes to PARALLEL handling within mn10300_adjust_sched_cost

2014-08-27  David Malcolm  <dmalcolm@redhat.com>

	* gcc/config/mn10300/mn10300.c (is_load_insn): Rename to...
	(set_is_load_p): ...this, updating to work on a SET pattern rather
	than an insn.
	(is_store_insn): Rename to...
	(set_is_store_p): ...this, updating to work on a SET pattern
	rather than an insn.
	(mn10300_adjust_sched_cost): Move call to get_attr_timings from
	top of function to where it is needed.  Rewrite the bogus
	condition that checks for "insn" and "dep" being PARALLEL to
	instead use single_set, introducing locals "insn_set" and
	"dep_set".  Given that we only ever returned "cost" for a non-pair
	of SETs, bail out early if we don't have a pair of SET.
	Rewrite all uses of PATTERN (dep) and PATTERN (insn) to instead
	use the new locals "insn_set" and "dep_set", and update calls to
	is_load_insn and is_store_insn to be calls to set_is_load_p and
	set_is_store_p.
