/**
 * @assertion If a class [C] in an opted-in library implements the same generic
 * class [I] more than once as [I0], .., [In], and at least one of the [Ii] is
 * not syntactically equal to the others, then it is an error if
 * [NNBD_TOP_MERGE(S0, ..., Sn)] is not defined where [Si] is [NORM(Ii)].
 * Otherwise, for the purposes of runtime subtyping checks, [C] is considered to
 * implement the canonical interface given by [NNBD_TOP_MERGE(S0, ..., Sn)].
 *
 * @description Check that error occurs in the following cases:
 *   NNBD_TOP_MERGE(Object*, int*)
 *   NNBD_TOP_MERGE(Object*, Function*)
 *   NNBD_TOP_MERGE(Object*, Null*)
 *   NNBD_TOP_MERGE(Object*, Never*)
 *   NNBD_TOP_MERGE(Object*, FutureOr<int>*)
