re PR target/77270 (Flag -mprftchw is shared with 3dnow for -march=k8)

	PR target/77270
	* gcc.dg/tree-ssa/loop-28.c: Also compile on 32bit x86 targets.
	(dg-options): Use -march=amdfam10 instead of -march=athlon.
	* gcc.dg/tree-ssa/update-unroll-1.c: Ditto.
	* gcc.dg/tree-ssa/prefetch-3.c: Ditto.
	* gcc.dg/tree-ssa/prefetch-4.c: Ditto.
	* gcc.dg/tree-ssa/prefetch-5.c: Ditto.
	* gcc.dg/tree-ssa/prefetch-6.c: Ditto.  Do not require sse2
	effective target.  Remove scan-assembler-times directives.
	* gcc.dg/tree-ssa/prefetch-7.c: Ditto.
	* gcc.dg/tree-ssa/prefetch-8.c: Ditto.
	* gcc.dg/tree-ssa/prefetch-9.c: Ditto.
