    tree-optimization/107095 - fix typo in .MASK_STORE DSE handling
    
    We were using the size of the mask argument rather than the data
    argument for the ao_ref.
    
            PR tree-optimization/107095
            * tree-ssa-dse.cc (initialize_ao_ref_for_dse): Use data arg
            for .MASK_STORE size.
