This avoids asserting anything on the SLP_TREE_REPRESENTATIVE of
an SLP permute node (which shouldn't be there).
Bootstrapped / tested on x86_64-unknown-linux-gnu, pushed.

* tree-vect-slp.c (vect_slp_analyze_node_operations_1): Move
assert below VEC_PERM handling.
* gfortran.dg/vect/pr99807.f90: New testcase.
