OverloadedRecordFields status update

[Adam Gundry]

Hi ghc-devs,

I have been working on a new extension, OverloadedRecordFields, and it
is now essentially feature-complete. Unfortunately, I doubt it will make
it into 7.8, as the changes are quite extensive, but I hope to get it in
HEAD soon thereafter.

I would really appreciate comments on the design [1], for which there is
a prototype implementation [2] that works in GHC 7.6.3. If you'd like to
review the code, you can check out the overloaded-record-fields branch
from the Github repositories [3, 4], and there are notes on the
implementation on the wiki [5].

Thanks!

Adam
