Trevor Norris ae196175f4 node: improve GetActiveRequests performance ...

v8 is faster at setting object properties in JS than C++. Even when it
requires calling into JS from native code. Make
process._getActiveRequests() faster by doing this when populating the
array containing request objects.

Simple benchmark:

    for (let i = 0; i < 22; i++)
      fs.open(__filename, 'r', function() { });
    let t = process.hrtime();
    for (let i = 0; i < 1e6; i++)
      process._getActiveRequests();
    t = process.hrtime(t);
    console.log((t[0] * 1e9 + t[1]) / 1e6);

Results between the two:

    Previous:  4406 ns/op
    Patched:    690 ns/op     5.4x faster
