Split LogArrayProvenance
Summary:
Two flags:
ArrayProvenance controls instrumentation of array provenance, period.
LogArrayProvenance controls logging.
There's some funny business where I turn off the instrumentation if was enabled
in the repo but we start HHVM without the logging enabled; or, if it wasn't
enabled when we built the repo.
Either way, if we're not loading from a repo, the options in the hdf are
respected without question :)
