remove SLP_TREE_TWO_OPERATORS, add SLP permutation node
This removes the SLP_TREE_TWO_OPERATORS hack in favor of having
explicit SLP nodes for both computations and the blend operation.
For this introduce a generic merge + select + permute SLP node
(with implementation limits).
Building upon earlier patches it adds vect_stmt_dominates_stmt_p
and the ability to compute a vector insertion place from
vectorized stmts (which now have UID zero) as needed for
the permute node.
