tree-optimization/117343 - decide_masked_load_lanes and stale graph

It turns out decide_masked_load_lanes accesses a stale SLP graph
so the following re-builds it instead.

PR tree-optimization/117343
* tree-vect-slp.cc (vect_optimize_slp_pass::build_vertices):
Support re-building the SLP graph.
(vect_optimize_slp_pass::run): Re-build the SLP graph before
decide_masked_load_lanes.
