Fix fallout from wildcards refactoring
The wildcard refactoring was introduced a new type of signature, `ClassOpSig`, which is carried by typeclasses. The original patch adapting Haddock for this change missed a few places where this constructor needed to be handled, resulting in no class methods in documentation produced by Haddock. Additionally, this moves and renames the `isVanillaLSig` helper from GHC's HsBinds module into GhcUtils, since it is only used by Haddock.
