The varnullingrels bitmapset is not only about outer joins

Hi,

designing things upon fresh master I found that varnullingrels contains 
numbers that is out of the outer joins index range.
Anywhere in documentation I see that this field contains outer join 
relids. But after the 247dea8 it simply isn't true.
So, I propose at least to change comments (see attachment). Since the 
doc was out of scope, I wonder if someone analysed the impact of this 
change on the whole optimiser logic.
