[parser] Eagerly throw pattern error even if we lazily throw lhs error for calls We don't eagerly throw for assignments to calls; see v8:4480. They are simply turned into assignments to Property instead. We need to record a declaration error, however. Otherwise we'll end up with a Property in a declaration context. To reduce the scope of the lazy throwing, in this fix I record a pattern error instead, making calls as assignment target in a destructuring assignment context throw eagerly.
