Allow more BB vectorization
The following allows more BB vectorization by generally building leafs
from scalars rather than giving up. Note this is only a first step
towards this and as can be seen with the exception for node splitting
it is generally hard to get this heuristic sound. I've added variants
of the bb-slp-48.c testcase to make sure we still try permuting for
example.

* tree-vect-slp.c (vect_build_slp_tree_2): Also consider
building an operand from scalars when building it did not
fail fatally but avoid messing with the upcall splitting
of groups.
* gcc.dg/vect/bb-slp-48.c: New testcase.
* gcc.dg/vect/bb-slp-7.c: Adjust.
