ping. This introduces a way to prevent InstructionSimplify from using metadata when simplifying for NewGVN. This fixes a correctness problem, where we currently make a simplification based on metadata of the leader, which not necessarily is available for all instructions in a congruence class. Any feedback on the general approach would be great.
