Note that in the current form it's not magically working for any frontend like you would expect: The MIR printing and verification at the end of a pipeline or loading a MIR file at the beginning of a pipeline is still done in `llc` even with this patch and would need to replicate that code in other frontends.
(If you're gonna adapt your frontends anyway, then you can do that even without this pass :)
