When the descriptor argument is undefined, the spec is very explicit about the
fact that we should return false (not true, like we did previously). I couldn't
come up with a test case for this, but the old code leaves a bad feeling about
corner cases, so better play safe.

Named function expression have an implicit local variable that
refers to the current function (ThisFunction). Before we only could inline
anonymous function expressions like:
A.prototype.foo = function() {}
as opposed to
A.prototype.foo = function foo() {}
This change enables inlining function of expressions like this.

If input string was cons-string it might undergo short-circuiting during GC. This does not change input start if underlying seq-string (first element of cons-string) does not move but this makes input-string pointer on the native regexp's frame invalid.

Recognize special comparisons via pattern matching on the hydrogen graph, 2nd attempt.

This time, we initially leave the HTypeof instruction in the Hydrogen graph,
even for the special cases. We later try to remove this instruction (and any
HConstant) in the canonicalization pass, if possible. Always removing the
HTypeof during the initial graph construction is wrong if e.g. it is used in an
HSimulate.
The removals can be generalized a bit, but this will happen in a separate CL.

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.

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.

Refactor how embedded pointers are visited.
...
This refactoring (almost) gets rid of the requirement to get the target
object address for an object pointer embedded in code objects. This is
not possible on MIPS as pointers are encoded using two instructions. All
usages of RelocInfo::target_object_address() are (almost) obsoleted by
this change. The serializer still uses it, so MIPS will not yet work
with snapshots turned on.

Don't count duplicate assignments to the same property as distinct ones.
...
In the ThisNamedPropertyAssignmentFinder, duplicate assignments to the same
property were counted as distinct assignments. As a simple fix, subsequent
ones overwrite the previously recorded assignment.
This will reorder the assignments, but it is safe since they are restricted
to have only constants and parameters on the right-hand side (and there are
no assignments to the parameters).
