All callable objects should have a global object reference
​https://bugs.webkit.org/show_bug.cgi?id=39495

All objects that may ever return a value other CallTypeNone
or ConstructTypeNone now get a global object in their constructor
and store that in their first anonymous slot. We add a new type
JSObjectWithGlobalObject to allow us to share this logic as much
as possible, however some objects have specific inheritance
requirements so we can't just use it universally.

To enforce this requirement JSValue::getCallData and getConstructData
make use of a new "isValidCallee" function to assert that any object
that returns a value other than CallType/ConstructTypeNone has a
global object in anonymous slot 0.

In order to ensure that static function slots are converted into
function objects with the correct global object, all prototype objects
and other classes with static function slots also gain a global object
reference. Happily this fixes the long standing issue where host
function objects get a prototype from the lexical global object of the
first function that calls them, instead of the global object that they
are defined on.
