This CL adds machinery to unwind stack handlers from the stack and store
them into a generator's operand array.  It also includes routines to
reinstate them.  Together this allows generators to yield within
try/catch and try/finally blocks.

Each SharedFunctionInfo gets an optimized code map to store
one optimized code object per context. When allocating a new
closure we consult this map and check if there is optimized code
that can be shared.

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.
