Type coercion of value returned by constructor's @@hasInstance property

1. If Type(C) is not Object, throw a TypeError exception.
2. Let instOfHandler be GetMethod(C,@@hasInstance).
3. ReturnIfAbrupt(instOfHandler).
4. If instOfHandler is not undefined, then
a. Return ToBoolean(Call(instOfHandler, C, «O»)).
