tree-optimization/99807 - avoid bogus assert with permute SLP node
This avoids asserting anything on the SLP_TREE_REPRESENTATIVE of
an SLP permute node (which shouldn't be there).
2021-03-29 Richard Biener <rguenther@suse.de>
PR tree-optimization/99807
* tree-vect-slp.c (vect_slp_analyze_node_operations_1): Move
assert below VEC_PERM handling.
* gfortran.dg/vect/pr99807.f90: New testcase.
