Move argument validation out of C++ and into JS. Improves performance
by about 15-20%.

Benchmark comparisons between current master and this branch are below:

$ node benchmark/compare.js ./node ./node_before  -- misc bench-hrtime
running ./node
misc/bench-hrtime.js
running ./node_before
misc/bench-hrtime.js

misc/bench-hrtime.js n=1000000: ./node: 13037000 ./node_before: 10677000 . 22.11%

@evanlucas this is not merging into v4.x-staging without conflicts. Would you be able to take a look and perhaps send a new PR against that branch?

Sure I'll try do get that done tonight.

@thealphanerd this one depends on 36e8a2c, which doesn't appear to have landed in v4.x-staging, so we should probably avoid backporting this one unless that one gets backported as well?

it looks like 36e8a2c is part of a series of six commits that were not landing cleanly. Work done by @trevnorris

Do you think that it is worth the effort to attempt to back port all of this?

I would say let's hold off for now.

As #3780 is now dont-land-on-v4.x I'm going to mark this one similarly
