r214187, thanks for noticing.

Did something quick in r214187 -- sufficient or do you think there should be
more?

> 3. The name is incredibly ambiguous; could it at least have a verb in it? It seems like it is a fuzzer that verifies that use-lists correctly round-trip through bitcode. Is there a better name? Maybe something with "verify" in it? (a long-ish name for a specialized tool like this wouldn't seem that out of place).

Here are two options:

  - verify-uselistorder
  - llvm-verify-uselistorder

Either of those sound better to you?
