Make setting of accessors even more atomic.

Now the whole getter/setter/attributes triple gets created/set together,
avoiding any hacks regarding previous values/attributes, making things a lot
simpler.

While doing this, an interesting problem surfaced, which has been there for a
long time: After adding/changing acessors in slow mode, we could potentially
fail going back to fast mode because of a failed memory allocation, signaling
the need for a GC. But we have already changed the object in slow mode, so we
are not idempotent and the retry would trigger a newly inserted assertion
(namely, that the code obeys access restrictions). This has been solved by
splitting the transformation to fast mode from the actual setting of the
accessors.

-utilized the delay slot of most Ret instructions
 This does not cover all Rets, only the most obvious cases.

Ensure that generated code for object literals will call Runtime_DefineOrRedefineAccessorProperty only once per accessor property.

To do this, we collect all accessor properties in a first pass and emit code for
defining those properties afterwards in a second pass.

As a finger exercise, the table used for collecting accessors has a (subset of
an) STL-like iterator interface, including STL-like names and operators.
Although C++ is quite verbose here (as usual, but partly this is caused by our
current slightly clumsy classes/templates), things work out quite nicely and it
cleans up some confusion, e.g. a table entry is not an iterator etc.
Everything compiles into very efficient code, e.g. the loop condition 'it !=
accessor_table.end()' compiles into a single 'testl' instruction on ia32.
+1 for using standard APIs!

Landing for pliard@chromium.org: Remove static initializers in v8.

This change includes two CLs by pliard@chromium.org:

1. http://codereview.chromium.org/9447052/ (Add CallOnce() and simple LazyInstance implementation):

Note that this implementation of LazyInstance does not handle global destructors (i.e. the lazy instances are never deleted).

This CL was initially reviewed on codereview.appspot.com:
http://codereview.appspot.com/5687064/

2.  http://codereview.chromium.org/9455088/ (Remove static initializers in v8):
This CL depends on CL 9447052 (adding CallOnce and LazyInstance).
It is based on a patch sent by Digit.

With this patch applied, we have only one static initializer left (in atomicops_internals_x86_gcc.cc). This static initializer populates a structure used by x86 atomic operations. It seems that we can hardly remove it. If possible, it will be removed in a next CL.

This CL also modifies the presubmit script to check the number of static initializers.
