Indeed that would be nice. The best there is is Andrew Tolmach's
external-core representation, which is described rather thoroughly
The various -ddump outputs are not well documented, and
change reguarly anyway. It's easier to agree that documentation
would be useful than to generate such documentation.
Let me make a constructive suggestion, though. Often people
learn stuff about GHC. There's an easy way for them to record
what they learned, by putting it in Manuel's GHC commentary:
Notes in the commentary don't need to be complete or
consistent -- but if you simply jot down (in HTML) the things

be incorporated and help the next person.
So send us your jottings! (For those with access to the CVS
