===== SUSPECTED CL(s) =====
Subject : Add [OverrideBuiltins] label onto HTMLDocument interface.
Author  : peria
Commit description:
  
This CL also removes special handling of named properties
using V8 script controller, which is no longer needed.

Currently, we have no general routines to work for [Unforgeable]
on [OverrideBuiltins] interface, and "location" in "HTMLDocument"
is the only one which meets the situation.
So now, we handle it as an edge case of named property.

Spec: https://html.spec.whatwg.org/multipage/dom.html#dom-document-namedItem-which

Updated a test expectation; Chrome has been FAILing it, while IE, FF, and Safari PASS it.

I reverted the change, and expect these performance get good back soon.

I also added a few Speedometer regressions which are recovered after the revert.
