I want to `suppress` a match failure (see changes in this differential). The transform pipeline should technically see the match failure and fail to perform any subsequent transformations (like how a normal pass pipeline would). I just want it to not bail out in the very end, and instead return the state the IR was in before the pipeline was applied.

More generally, if I have to apply different pipelines in some priority order (the first one to succeed will change the IR, and the rest of the pipelines will not be applied), how do I do that? (In my case, the second pipeline is a no-op transformation.)
