Test case:
---
async function f() {
    (...await) => {};
}
---

Expected: Throws SyntaxError
Actual: No SyntaxError thrown

"await" only matches BindingIdentifier when [Await] is not present.

This is basically the same issue as bug 1353691: If we set [Await] when parsing the arrow parameters, we'd throw a SyntaxError.
