testsuite: Adjust vect/bb-slp-subgroups-3.c for VL vectors

Because we disable the cost model, targets with variable-length
vectors can end up vectorising the store to a[0..7] on its own.
With the cost model we do something sensible.

	* gcc.dg/vect/bb-slp-subgroups-3.c: XFAIL for variable-length vectors.
