	PR middle-end/44185
	* gcc.dg/tree-ssa/prefetch-7.c: take the loops that will generate
	non-temporal stores out of the tests to form new test cases.  As a
	result, no non-temporal store should be generated in this case.

	* gcc.dg/tree-ssa/prefetch-8.c: New.  Test from original
	prefetch-7.c that generate one non-temporal store.

	* gcc.dg/tree-ssa/prefetch-9.c: New.  Test from original
	prefetch-7.c that generate one non-temporal store and one
	one-temporal prefetch.
