7d681e014d Compile FastCloneShallowObjectStub using Crankshaft. 
This changes FastCloneShallowObjectStub to be compiled independent of
the target architecture. It also adds tracing to the deoptimizer for
compiled stubs and contains some minor bugfixes.

95c5e68714 Fix bogus regexp test. 
The reason this test fails on ARM hardware but not on Intel hardware
(including the ARM simulator) is this:
'\xa0' is interpreted as a negative signed byte number. Casting it to
uc16 sign-extends it. The resulting string does not fit into a one-byte
string, thus a two-byte string is allocated.
For some reason the code compiled for ARM does not sign-extend, and 0xa0
fits into a one-byte string. Thus a one-byte string is allocated. Trying
to cast it to two-byte causes assertion failure.

ce1e10f5fc Make __proto__ a foreign callback on Object.prototype. 
This moves the __proto__ property to Object.prototype and turns it into
a callback property actually present in the descriptor array as opposed
to a hack in the properties lookup. For now it still is a "magic" data
property using foreign callbacks and not an accessor property visible to
JavaScript.

The second effect of this change is that JSON.parse() no longer treats
the __proto__ property specially, it will be defined as any other data
property. Note that object literals still have their special handling.

8f407c7b99 Move extensibility check to the top of Object.isFrozen/Object.isSealed 
This speeds up isFrozen/isSealed checks on "normal" objects without
slowing down checks on frozen/sealed objects.

Though this ordering is not what ES5 specifies, the difference is not
observable (especially since the code bails out if the passed-in object
is a proxy).

30a4a798e5 Speed up non-interceptor case of Object.getOwnPropertyNames 
When there are interceptors on an object, it's possible to
end up with duplicate property names. But when all the names
are provided by v8, a collision is not possible, so we can
fast-path that case by not de-duping.

Also added better test coverage for interceptor API.

9ebcfb41e2 ARM: Make DoStoreKeyedFixedDoubleArray faster; don't allow conditional Vmov 
This patch makes us generate faster code for DoStoreKeyedFixedDoubleArray,
by using a branch rather than a conditional Vmov instruction.

Conditional VFP instructions are not a great idea in general, and it was
especially bad in this case because Vmov expands to a bunch of instructions.
For this reason, the patch also removes the 'cond' parameter from Vmov.

Thanks to Rodolph for pointing me to this!

Isolate::Current()s had to be introduced, which is not nice, and not every place
will win a beauty contest, but we can clean this up later easily in smaller steps.
