I didn't get a lot of comments on my the previous version of my patch
to accelerate table locks.

Here's a new version anyway.  In this version, I have:

1. Made pg_locks show fast-path locks as well as regular locks, with a
new Boolean column to distinguish.
2. Renamed fpLWLock to backendLock, on the belief that we're going to
want something like this for quite a bit more than just this one
3. Removed some debugging code.
