The background here is that graphs generated from WASM are not trimmed. That means there can be some floating control diamonds that are not reachable from end. An assertion in the scheduler for phis from floating diamonds checks that the use edge in this situation is the control edge, but in general, any edge could cause this. Scheduling still works without this assertion. The longer term fix is to either trim the graphs (more compile time overhead for WASM) or improve the scheduler's handling of dead code in the graph. Currently it does not schedule dead code but the potential use positions of dead code are used in the computation of the common dominator of uses. We could recognize dead nodes in PrepareUses() and check in GetBlockForUse() as per TODO.
