    [turbofan] Initial version of RedundancyElimination. · 5250da68
    bmeurer authored
    The redundancy elimination is currently a graph reducer that tries to
    combine redundant checks in the effect chain. It does this by
    propagating the checks that happened along effect paths, which is pretty
    similar to what the BranchElimination does on the control chain. We run
    this reducer together with the other optimizations right after the
    representation selection.
    
    An upcoming CL will extend the redundancy elimination to also eliminate
    redundant loads (and eventually map checks).
