Subject: [PATCH] Wrong computation of the up/down dogleg layer for 2 layers
 gauges.

* Bug: In Anabatic::AutoHorizontal::_makeDogleg(), the up/down flag
    was incorrectly computed when the RoutingGauge RL where not the
    lower one. This was leading to making doglegs in non-routable
    layers (but present in the gauge for other purposes).
