    Fixup wrong change to get_group_load_store_type
    
    The following fixes up the r16-2593-g6ac78317aa6adf change which
    made us match up a scalar with a vector type.  Oops.
    
    Noticed when removing the gather/scatter pattern that creates the
    IFNs early.
    
            * tree-vect-stmts.cc (get_group_load_store_type): Properly
            compare the scalar type of the gather/scatter offset to
            the offset vector component type.
