commit 96be7a17790700998e2d071e00ad5c1ffb4a2d3e

    Handle un-normal zeros properly in the division-free elimination.
    
    Call .normal() instead of just .expand(), such that matrix::pivot() finds
    the pivot.
    
    Note that this problem also affects matrix::solve() with 'algo'
    set to solve_algo::automatic.
    
    Of course, using .normal() makes division_free_elimination only
    truly "division-free" if the input matrix didn't have fractions.
    In other cases, GCDs will be computed.
