Refactor SLP permute opt propagation
This rewrites the SLP permute opt propagation to elide the visited
bit for an incoming permute of -1 as well as allowing the initial
propagation to take more than one iteration before starting on
materialization. As we still lack propagation in the reverse
direction I've added gcc.dg/vect/bb-slp-71.c and a stopgap to
restrict "any" permute handling to the supported cases.
