tree-optimization/101264 - rework SLP "any" permute forward prop
This integrates the forward propagation of SLP "any" permutes into
the main propagation stage as a separate single-pass propagation
didn't work out.

* tree-vect-slp.c (vect_optimize_slp): Propagate the
computed perm_in to all "any" permute successors
we cannot de-duplicate immediately.
