Object.values is faster than fast.values

[baptistemanson]

The new function Object.values is x2 faster than fast.values on v8.

    ✓  Native Object.keys().map() x 5,834,570 ops/sec ±0.29% (97 runs sampled)
    ✓  Native Object.values()) x 23,794,424 ops/sec ±0.29% (99 runs sampled)
    ✓  fast.values() x 11,353,450 ops/sec ±0.65% (94 runs sampled)
    ✓  underscore.values() x 5,779,038 ops/sec ±0.46% (94 runs sampled)
    ✓  lodash.values() x 3,933,563 ops/sec ±1.49% (96 runs sampled)

Maybe we could shim it in fast.js like Object.keys?
