Not being a Rust person, I can only guess based on random pattern
matching, but this _looks_ like these "panicking intrinsics" panic at
run-time (by calling BUG()).

Is there some way these things could cause built-time link errors
instead, so that if somebody uses 128-bit shifts, or floating point
ops in the rust code, they show up as build failures, not as run-time
