5e96a8ca4b Temporarily allocate all function contexts in old space and 
force the system to use the full compiler to momentarily get 
better test coverage.

This change will be reverted once the unit tests have finished
running.

2a8034c8f6 Correctly set eval_from_shared value when new function is created by "new Function(...)". At the moment it's set to the native script where the Function is defined(v8natives.js) which doesn't make much sense for the user when he tries to debug his code. Moreover, it causes an exception in JSONProtocolSerializer.prototype.serialize_.

048fe9b980 RFC: Try to be much more careful with where we skip the write barrier by: 
1. Avoid using SKIP_WRITE_BARRIER when we don't have to (smis).
  2. Check and document the remaining uses of SKIP_WRITE_BARRIER.
  3. Only allow GetWriteBarrierMode when in an AssertNoAllocation scope.

The only functional change should be in DeepCopyBoilerplate where we
no longer use the write barrier mode (because of allocations). I'm
running benchmarks to see if this has a measurable impact on performance.

97e3aae5ef Refactoring and small optimization of the smi code for binary op stubs 
on ia32.

1. Operate on the values in edx,eax when possible (all operations
except DIV and MOD).  This saves moving them on entry and when falling
out to the non-smi code.

2. Do not perform ADD and SUB before the smi check of their inputs.
This saves undoing the operation in the case that we fall through to
the non-smi case due to non-smi inputs (probably common?), and we can
avoid emitting the smi check code twice (code size reduction).

3. Don't perform OR twice (once to smi check the inputs and once to
smi check the result).

cf78ed05ee Don't pass the "at start" parameter to native RegExp 
As the start index is already passed it is easy to calculate the "at start" boolean in generated code. Also as direct entry has been implemented this needs to be done in generated code anyway, and therefore might as well be moved to the generated code for RegExp. The "at start" value is now calcualted as a local variable on the native RegExp frame based on the value of the start index argument.

The x64 version have been tested on both Linux and 64-bit Windows Vista.

For ARM I have tested cctest/test-regexp on ARM hardware, but the rest of the tests have only been run on the ARM simulator.
