Make the PR99220 fix more robust
This avoids interleaving pattern recognition and load redistribution
optimization since the load_map used in the latter is fragile with
respect to release and reuse of SLP nodes, something which can also
occur within the pattern recognition machinery.

* tree-vect-slp.c (optimize_load_redistribution_1): Delay
load_map population.
(vect_match_slp_patterns_2): Revert part of last change.
(vect_analyze_slp): Do not interleave optimize_load_redistribution
with pattern detection but do it afterwards. Dump the
whole SLP graph after pattern recognition and load
redistribution optimization finished.
