Handle NULL stmt in SLP_TREE_SCALAR_STMTS
The following starts to handle NULL elements in SLP_TREE_SCALAR_STMTS
with the first candidate being the two-operator nodes where some
lanes are do-not-care and also do not have a scalar stmt computing
the result. I originally added SLP_TREE_SCALAR_STMTS to two-operator
nodes but this exposes PR115764, so I've split that out.
I have a patch use NULL elements for loads from groups with gaps
where we get around not doing that by having a load permutation.
