llvm dev - Jul 2018 - Marking lit::shtest-format.py unsupported on PS4?, Re: buildbot failure in LLVM on llvm-clang-lld-x86_64-scei-ps4-ubuntu-fast

Should "lit :: shtest-format.py" (from check-lit) be marked
unsupported on PS4?  It seems flakey there.

This evening, it failed on my commit, r337514, and I'm fairly confident it
wasn't my commit's fault.  Then it recovered on the next commit.

I've had a suspicion for a while that it's unstable *everywhere*. At
least, I've seen it fail on out-of-tree bots intermittently but haven't
had time to investigate. It certainly seems to fail very infrequently
though.

FWIW, I've seen it fail on some of my commits too, but I don't remember
whether it was on the PS4 bot exclusively or not. Anyway, my understanding
is that this test shouldn't inherently have different behaviour on PS4
specifically, but I could be mistaken. I suspect it's something more
general to do with the configuration of the bot.
