refactor SLP permute propagation

This refactors SLP permute propagation to record the outgoing permute
separately from the incoming/materialized one.  Instead of separate
arrays/bitmaps I've now created a struct to represent the state.

* tree-vect-slp.c (slpg_vertex): New struct.
(vect_slp_build_vertices): Adjust.
(vect_optimize_slp): Likewise.  Maintain an outgoing permute
and a materialized one.
