Add forward propagation to SLP "any" permutes
This adds a forward propagation phase to the permute optimization
machinery which allows us to handle "any" permute for all kinds of
nodes. To match previous behavior cost-wise we still do not allow
non-external/constant nodes to be duplicated for multiple permutes
and this is ensured during propagation itself.

* tree-vect-slp.c (vect_optimize_slp): Forward propagate
to "any" permute nodes and relax "any" permute proapgation
during iterative backward propagation.
