tree-optimization/101615 - SLP permute opt of existing vectors
This fixes one issue discovered when analyzing PR101615, namely
we happily push permutes to pre-existing vectors but end up
not actually permuting them. In fact we don't want to, so force
materialization on the external.
It doesn't fix the original testcase though.

* tree-vect-slp.c (vect_optimize_slp): Pre-existing vector
external nodes cannot be permuted so make them perm_out 0.
* gcc.dg/vect/bb-slp-pr101615-1.c: New testcase.
