Since SameValue algorithm is defined formally in ECMA262 and V8 already
exported Equals and StrictEquals algorithms, SameValue should be exposed.
And in this issue, we fix the issue of Object::SameValue implementation,
SameValue(0.0, -0.0) returnes true.

This is a fix for performance regression. For new Uint8Array(arrayLike)
and the likes, we allocate the backing store of typed array
uninitialized and then proceed to feel it in with elements of arrayLike.
If the loop over arrayLike runs to completion, we know that all elements
of typed arrays had been assigned to and there is no uninitialized
memory. If the loop does not run to completion, we propagate the
exception to constructor caller, therefore the typed array is not
exposed to user program.
