[PATCH] Fix PR68707

Browse Source 
gcc/:
	* tree-vect-slp.c (vect_analyze_slp_instance): Cancel permuted SLP
	instances that can be handled via vect_load_lanes.

gcc/testsuite/:

	* lib/target-supports.exp (check_effective_target_vect_load_lanes): New.
	* gcc.dg/vect/slp-perm-1.c: Look for vect_load_lanes instead of SLP
	on platforms supporting it.
	* gcc.dg/vect/slp-perm-2.c: Likewise.
	* gcc.dg/vect/slp-perm-3.c: Likewise.
	* gcc.dg/vect/slp-perm-5.c: Likewise.
	* gcc.dg/vect/slp-perm-7.c: Likewise.
	* gcc.dg/vect/slp-perm-8.c: Likewise.
	* gcc.dg/vect/slp-perm-6.c: Look for vect_load_lanes in addition to SLP
	on platforms supporting it.
