RegExpParser: Fix Reset()ting to the end.

The bug would occur when we try to Reset() to a position already at the end.

This happens e.g., when the regexp ends with \u. What used to happen in that
case: 1) Advance past \ and u (to the end) (which wouldn't increase next_pos_
enough) 2) Try to parse 4 hex digits 3) When that failed, Reset() to the
position which should've been at the end but wasn't.

To be able to properly Reset() to a position at the end, we need to allow
next_pos_ to move beyond the end (since position() is next_pos_ - 1).

Minimal repro case:

var r = /foo\u/
r.test("foou") // should be true, was false.

(Note that \u not followed by 4 hex didits should be interpreted as an identity
escape. It already worked unless \u was at the end of the regexp.)

build is the third number of the V8 version, and very likely to change

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.

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.

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.
