commit 540ffaa0d720ed04bb083857230ecd583662f8cc
Author: Richard Biener <rguent...@suse.de>

    Handle non-grouped SLP stores
    
    The following adjusts vectorizable_store to properly handle
    non-grouped SLP stores to update vec_num.
    
            * tree-vect-stmts.cc (vectorizable_store): Always set
            vec_num for SLP.
