tree-optimization/98544 - more permute optimization fixes
Permute nodes are not transparent to the permute of their children.
Instead we have to materialize child permutes always and in future
may treat permute nodes as the source of arbitrary permutes as
we can permute the lane permutation vector at will (as the target
supports in the end).

permutes at a permute node.
* gcc.dg/vect/bb-slp-pr98544.c: New testcase.
