Fixing _isSync bug where a single was thought to be a sync as well [reviewed by vass]

Vass discovered that _isSync was printing out true for singles as well as syncs.
This was because the FLAG_SYNC was attached to both and my compiler primitive
was looking for the presence of the flag rather than if it had that flag and was
not a single.  I fixed this by removing FLAG_SYNC from singles and replacing the
one instance where only FLAG_SYNC was used to now check for either FLAG_SYNC or
FLAG_SINGLE.  This resolved that portion of the bug.

Expanded future_stats to give more stats

This script now gives total future counts, as well as how many of each
kind that are not documented in the STATUS file.  In addition, print
out names of "uncategorized" tests, i.e. those that do not match any
of the various documented tags.
