If we do, we can end up with inst1 --------------- < Insertion point dbg inst new inst instead of the desired inst1 new inst --------------- < Insertion point dbg inst Another option would be for InsertNoopCastOfTo (or its callers) to move the insertion point and we would end up with inst1 dbg inst new inst --------------- < Insertion point but that complicates the callers.
