tree-optimization/115508 - fix ICE with SLP scheduling and extern vector
When there's a permute after an extern vector we can run into a case
that didn't consider the scheduled node being a permute which lacks
a representative.
PR tree-optimization/115508
* tree-vect-slp.cc (vect_schedule_slp_node): Guard check on
representative.
* gcc.target/i386/pr115508.c: New testcase.
