Sure - we've been missing that for a long time.

If a user sees a warning that says: `Name conflict, use --nameless-prefix=XXXXX, where XXXXX is a string not otherwise used in your IR`, they will happily do so. The UTC_ARGS extension makes it permanent and no one needs to worry about this until they see a warning again. (If we can "hide" the option from the help message, I'm fine with that too.)

I'm still not convinced that's worth doing. I did change instnamer though:

...so between the warning and at least 1 of these not using 'tmp', I think we're good enough.

Yep, I didn't remember that we had tests for scripts. So we have that now, and there's a clang test that wiggles on this too...although that seems like we should generalize that file to avoid killing all of the bots like I did. :)
