This fixes updating of property attributes for getters and setters on

This is reapplying r9501 with this single change which seemed to be causing most (all) of the failures for r9501.

456e5e00c3 Fix assert by reordering the initialization of the arguments boilerplate. 
If a GC happened during initialization (when allocating the elements array)
of the non_strict_arguments_boilerplate, heap verification would fail with the following assert:

ASSERT_EQ((map()->has_fast_elements() || map()->has_fast_smi_only_elements()),
            (elements()->map() == GetHeap()->fixed_array_map() ||
             elements()->map() == GetHeap()->fixed_cow_array_map()));

This was not harmful since the boilerplate was setup 
correctly immediatly afterwards.


Simplified the setup code by removing a call to GetElementsTransitionMap. It always return the same map as 
the input object in this case and is therefore unnecessary.


Added more assertions to verify well-formed non-strict
arguments backing store.

BUG=v8:1520
TEST=no more flaky tests with failing this assert.

2bbf3bbee7 Make native syntax an early error in the preparser. 
Previously the preparser always accepted natives syntax and let the
real parser throw the syntax error. In ES5, it should be an early error,
so the preparser must catch the error.
The perparser library does not expose parsing for natives syntax, it's
only used internally.

baa29ebafa Recognize special comparisons via pattern matching on the hydrogen graph. 
Previously, comparisons against null/undefined and comparisons of the result of
typeof against a constant string were done syntactically. Now we do this via
pattern matching on the hydrogen graph, which opens up more opportunities for
better code generation, e.g. the following comparisons are now recognized to be
special:

   var bar = typeof foo;
   var baz = "undefined";
   if (bar == baz) ...

   var blah = undefined;
   if (hurz == blah) ...

If we did this handling of special cases even later at lithium generation time,
even more cases could be recognized, but this would involve bigger changes and
this CL handles most common cases.
