I have not reviewed this PR, yet, but I just want to raise a general concern that our model of having different `PrintIdealGraphLevel` values might not fit anymore for all the different concepts (different loop opts, IGVN steps, Superword steps, parsing steps and now EA steps etc.). Maybe the time has come to use a different solution to allow some better filtering for different needs. It should not per se block this PR but could be a justification to actually tackle this.
