Message:

JSValueProtect and JSValueUnprotect don't protect API wrapper values
​https://bugs.webkit.org/show_bug.cgi?id=31485

Reviewed by Geoff Garen.

Make JSValueProtect/Unprotect use a new 'toJS' function, 'toJSForGC' that
does not attempt to to strip out API wrapper objects.
