  -----------
  [Site-Isolation] RemoteDOMWindow::setLocation should have identical security 
checks as LocalDOMWindow::setLocation
rdar://116500603
https://bugs.webkit.org/show_bug.cgi?id=296457

Reviewed by Alex Christensen.

Move a number of functions which check security of setLocation from 
LocalDOMWindow to DOMWindow parent class and invoke them in a new 
setLocationSecurityChecks function which is called in both 
LocalDOMWindow::setLocation() and RemoteDOMWindow::setLocation().
