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!

This uses the type feedback already present for computed value stores
into object literals to generate optimized stores in Crankshaft, thus
avoiding unnecessary generic stores with side effects.

Ensure there is a smi check of the receiver for global load and call ICs.

There was a comment that, for such ICs specialized to the global object,
they were always contextual loads.  This is very brittle.  It is a
micro-optimization that relies too much on the way that things happen to
work today.

Instead, never omit the smi check because it's safer.

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.

knowing that 'r1', 'r2' and 'r3' is used/destroyed in inline asm,
compiler assumes that 'r1', 'r2', or 'r3' can be used exclusively,
