a32291fa1f Stop sending Object.observe notifications for API accessor properties 
Such properties never notified prior to r21558, but the combination of
that change and r23163 led to sending notifications when they were
set via Object.defineProperty (but not when set via other means).

This also allows some cleanup in v8natives.js and objects.cc,
both of which were doing unnecessary contortions to produce the right
change records.

7c42ae3e47 Fixed an ordering issue found by UBSan_vptr. 
We managed to access the scope_ member of CompilationInfo before its
containing object was actually constructed.

Rule of thumb: When constructing an object, never ever pass around
pointers to members which come later in the member initializer list,
you simply can't see locally if this might cause trouble or not.

71bb00e261 Consistently use only one of virtual/OVERRIDE/FINAL. 
FINAL implies OVERRIDE, which in turn implies virtual, so there's no need to use
more than one of these. The Google C++ style guide even requires this, see
http://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Inheritance.

While we're here, port r24662 to x87.

The net result is that v8 compiles again with a current clang.
