Permitting trailing commas for record syntax ADT declarations

[Johan Tibell]

+1

I think this makes sense and we should allow trailing commas wherever the
syntax allows it without adding ambiguity (e.g. tuple sections prevent
trailing commas for tuple declarations.)

P.S. Last time we tried to discuss something like this (on libraries@ I
believe) the whole discussion devolved into a "lets rewrite all of
Haskell". Lets not do that here. Thanks!
