The existing PropertyQueryCallback intercepts getOwnPropertyDescriptor, but
it returns only value and attributes, not the accessors. This
PropertyDescriptorCallback returns a descriptor similar to Ecma-262 6.2.4.

You can either set a PropertyQueryCallback or a PropertyDescriptorCallback,
but not both. When you set a callback for DefineProperty(), you can set a
PropertyDescriptorCallback but not a PropertyQueryCallback.

This clears the context register by setting it to Smi(0) before calling
the Runtime::kNotifyDeoptimized helper. The deoptimizer must be able to
materialize all heap objects without any context available. The context
itself might be dematerialized.

With this change we make sure that invariant is maintained even without
escape analysis kicking in. We also satisfy the check that the context
register is either Smi(0) or a valid context. It might have been the
special {arguments_marker} in this particular case.

The optimization is not correct for unsigned output types, and we the
overall complexity seems too high. We need to find a better way to
take into account the input/output type restrictions.

Also added a regression test for the unsigned output bug.

The trouble here is that the type of the induction variable might be
a bit ahead of the increment (JSAdd) operation's type. When we update
the type of the increment, we might only update the induction variable
type while the JSAdd type might be stale. If the induction variable typing
needs to fall back to normal phi typing (e.g., when the increment is not
an integer anymore), it might use the stale type.

To get around this, we fake monotonicity if we fallback to normal phi
typing. Another option would be to force re-typing of the increment
operation, but that seems to be harder to maintain.

On PPC the testcase CodeSerializerLargeCodeObject fails as
the object gets allocated in the code_space section of
the heap. This is because the code_space gets expanded
successfully to 1 page size (4MB on PPC) and can accommodate
the object (size=3784608 bytes). Increasing size of the compiled
source to (5096192 bytes) so that code_space is not expanded and
the space is allocated in the Large Object space of the heap.

We were previously incorrectly changing:
  sub r0, 0, r1
  cmp r2, r0
  b.cond <addr>
to:
  cmn r2, r1
  b.cond <addr>

for all conditions. This is incorrect for conditions involving the C (carry)
and V (overflow) flags, and in particular in the case where r1 = INT_MIN.
The optimization is still safe to perform for Equal and NotEqual since they
do not depend on the C and V flags.

Migrate the isNaN, isFinite, Number.isFinite, Number.isInteger,
Number.isSafeInteger and Number.isNaN predicates to TurboFan
builtins and make them optimizable (for certain input types) in
JavaScript callees being optimized by TurboFan. That means both
the baseline and the optimized version is now always at maximum,
consistent performance. Especially TurboFan suffered from poor
baseline (and optimized) performance because it cannot play the
same weird tricks that Crankshaft plays for %_IsSmi.

This also adds a bunch of new tests to properly cover the use
of the Harmony predicates in optimized code.
