The new implementation:
* uses MemoryBarriers to make sure up-to-date data is accessed on both producer and consumer threads
* will not allow to overwrite records
* doesn't have notion of chunks, instead each entry is aligned on the cache line boundaries

From now on the v8config.h header should be the one and
only file where we do (freaky) checks to detect OS, C++
compiler or certain compiler features. Since we need that
both internally and for the public API, the new v8config.h
is the proper place to add (everything is prefixed with V8_
so we are safe).

We do not use rdtsc anywhere and we won't ever use that in the

This consists basically of 2 parts:

   * Restructured BuildCompareNil to make the logic behind it clearer.
     Note that it is intentionally written in a quite stylized way.

   * Replaced a usesless IfBuilder by a plain HInstruction, removing
     some empty blocks.

We shouldn't need to know whether to use --no or --no- as prefix.
The latter is more intuitive and also what chromium uses.

The primary reason for this change is to bake these guys into the
snapshot.

Flag definitions (--harmony-typed-arrays, --harmony-array-buffer) are
still there so that Blink does not complain, but they are noop and

This is an attempt to fix a weird perf regression on MacOS X 10.6 bot.
Perf regression is not reproducible on MacOS X 10.8.
This difference in memory-copying routines is the only reasonable
difference in the algorithm. We should try and see.
