[lldb-dev] test results look typical?

Can't comment on the failures for Linux, but I don't think we have a good
handle on the unexpected successes.  I only added that information to the
output about a week ago, before that unexpected successes were actually
going unnoticed.

It's likely that someone could just go in there and remove the XFAIL from
those tests.
