> Can we move these warn to common.py?
Come to think of it, maybe moving it to common.py was not quite ideal:
- once a warning is issued in the middle of the list of RUN lines, it'll just be re-issued next time around; we could warn and exit, but that'd be annoying if there's another failure later in the RUN list.
- if we do it at the end, we can additionally distinguish the case where a prefix has an empty dict of funcs associated with it -> and the warning would be "there are unused prefixes - please remove %s'. This is more discoverable than llvm-lit -a, and also than relying on the user knowing to run uplate_test_prefix.

I think that the benefits (discoverability, better, more concise warnings) make the extra 2-3 lines worth it; and we already have tests for these other tools - wdyt?
