We do not support the caller information for functions, and since a
'null' value represents that there has been no caller, the default value
should be changed to 'undefined' to signal that the information is not
available.

2nd and 3rd argument evaluation of Array.prototype.copyWithin can change
the length of the array as a side-effect. But ES11 spec says that the
algorithm should use the original length. In this case it could happen
that the underlying buffer should be extended.

If the prototype of a fast array is changed, for example to a Proxy object,
the array should be converted back to a normal array. This is required to
correctly handle any [[Get]]/[[Set]]/etc... calls which should trigger
these method calls on the before mentioned Proxy object.

In case of Proxies the "ownKeys" call can return an incompatible
value for a for-in statement. In such cases the error should be
propagated to the user.
