[lldb-dev] lldb test suite on macOS 10.13 (High Sierra)

[Pavel Labath via lldb-dev]

On a somewhat tangential note:

Is anyone actually using this crashinfo hook? It looks like this could
be useful in the old dotest days, when we were running all of the
tests in a single python process, but now with the parallel test
runner spawning a new process for each test file and with piping test
results through a socket, it seems much less useful. If noone is using
that functionality, maybe we could "fix" the problem by deleting it.
