/// @assertion Let e be a setOrMapLiteral
/// ...
/// If e has typeArguments then:
///   - If there is exactly one type argument T, then e is a set literal with
///     static type Set<T>.
///   - If there are exactly two type arguments K and V, then e is a map literal
///     with static type Map<K, V>.
///   - Otherwise (three or more type arguments), report a compile-time error.
///
/// @description Checks that it is a compile-time error if an
/// emptySetOrMapLiteral has a typeArguments with more than two type arguments.
