More consistently split SLP groups

This appropriately makes matches all true after successful SLP discovery
to reliably succeed splitting.  We were picking up an eventual all
false built-up from scalars state in some cases.

* tree-vect-slp.c (vect_analyze_slp_instance): Set matches to true
after successful discovery but forced split.
