#2905: require -XGADTs in order to pattern-match GADTs

Comment (by Dominic):
I would vote for requiring the -XGADTs flag if you are using GADTs not
merely defining them. Either that or a better suggestion on the error
message (although this might be annoying for real "GADT pattern match in
non-rigid context" errors).
