[parser] Fix cover-grammar initializer positions Since we use a ScopedPtrList to track cover grammar expressions we don't know the position of the commas anymore. The position of the commas was used to demark the initializer, which is needed to figure out whether we need hole checks for variable references. (Typically only references within the initializer need hole checks for the initialized variable.) Since we didn't have the comma position, we simply used the position of the first expression as the position of any subsequent comma, which would make it seem as if the initializer body wasn't in the initializer. Now instead we simply use the position of the subsequent parameter as the end of the initializer, which is close enough.
