Hi hackers,

Several times now when reading, debugging and writing code I've wished
that LWLockHeldByMe assertions specified the expected mode, especially
where exclusive locking is required.

What do you think about something like the attached?  See also an
example of use.  I will add this to the next commitfest.

I've wanted this before too, and was surprised it wasn't present. TBH I assumed there was a technical reason it wasn't and didn't investigate further because I just assumed it'd have been added with the original LWLockHeldByMe if it were simple.
