tree-optimization/101028 - fix endless SLP reassoc discovery
This fixes a missing clearing of mismatched lanes from the
fatal fail path in SLP reassoc discovery in the most conservative
way.

* tree-vect-slp.c (vect_build_slp_tree_2): When SLP
reassoc discovery fails fatally, mark appropriate lanes
in matches[] so.
* gcc.dg/pr101028.c: New testcase.
