Previously we'd first accumulate errors to the parent and validate the destructuring pattern in the parent. In the case of ParseArguments this will invalidly propagate binding pattern errors from one argument to the next. The reason why ParseArguments keeps track of binding pattern errors is because it could also be used to parse async arrow function parameters. If we see async(a,b) we don't yet know whether this is the head of an async arrow function, or a call to async with arguments a and b.
