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.
