    middle-end: Fix mask length arg in call to vect_get_loop_mask [PR96342]
    
    When issuing multiple calls to a simdclone in a vectorized loop,
    TYPE_VECTOR_SUBPARTS(vectype) gives the incorrect number when compared
    to the TYPE_VECTOR_SUBPARTS result we get from the mask type derived
    from the relevant `rgroup_controls' entry within `vect_get_loop_mask'.
    
    By passing `masktype' instead, we are able to get the correct number of
    vector subparts and thu eliminate the ICE in the call to
    `vect_get_loop_mask' when the data type for which we retrieve the mask
    is wider than the one used when defining the mask at mask registration
    time.
