Yes, exactly, I took the fallback rules for
selectand duplicated them for x86-64, aarch64, and riscv64 (s390x already supported the general case).perhaps we should adopt the principle/goal that all combinations of CLIF which pass the validator should be implemented in any tier 1 backend? Whenever we fail that, it means we need to either change the instruction set, change the validator, or change the backend.
That sounds like a reasonable principle to me!

@fitzgen or @elliottt, would either of you be willing to review this?

Ah I thought that Jamey already reviewed it so I didn't leave a comment. Unclear to me whether Jamey wants changes on this PR after their review or not?

I interpreted @jameysharp 's reply as: no changes needed, approach is fine, but:
That makes sense to me, at least for now. But I don't feel comfortable reviewing the actual implementations.
FWIW, the implementations are identical to the existing
selectcases in each backend, so hopefully these aren't too hard to review!
