Change the way we split stores in BB vectorization
The following fixes missed optimizations due to the strange way we
split stores in BB vectorization. The solution is to split at
the failure boundary and not re-align that to the initial piece
chosen vector size. Also re-analyze any larger matching rest.

* tree-vect-slp.c (vect_build_slp_instance): Split the store
group at the failure boundary and also re-analyze a large enough
matching rest.
* gcc.dg/vect/bb-slp-68.c: New testcase.
