parser: opt_kind_sig has incorrect SrcSpan
The production for opt_kind_sig is
opt_kind_sig :: { Located (Maybe (LHsKind RdrName)) }
: { noLoc Nothing }
| '::' kind {% ajl (sLL $1 $> (Just $2)) AnnDcolon (gl $1) }
The outer Location is used only to get the full span for the enclosing declration, and is then stripped. The inner LHsKind then has a SrcSpan that does not include the '::'
Extend the SrcSpan on $2 to include $1
