tree-optimization/111136 - STMT_VINFO_SLP_VECT_ONLY and stores
vect_dissolve_slp_only_groups currently only expects loads, for stores
we have to make sure to mark the dissolved "groups" strided.
PR tree-optimization/111136
* tree-vect-loop.cc (vect_dissolve_slp_only_groups): For
stores force STMT_VINFO_STRIDED_P and also duplicate that
to all elements.
