    tree-ssa-math-opts: Use element_precision.
    
    The recent TYPE_PRECISION changes to detect improper usage
    cause an ICE in divmod_candidate_p for RVV when called with
    a vector type.  Therefore, use element_precision instead.
    
    gcc/ChangeLog:
    
            * tree-ssa-math-opts.cc (divmod_candidate_p): Use
            element_precision.
