This commit takes advantage of the performance improvements V8 has
made to function.bind() in V8 5.4 and uses it to avoid constant
recompilation/reoptimization of the wrapper closure used in once().
This change results in ~27% performance increase for once().

assertSize() is adjusted to be inlineable according to V8's default
function size limits when determining inlineability. This results in
up to 11% performance gains when allocating any kind of Buffer.
Avoid avoids use of in, resulting in ~50% improvement when creating
a Buffer from an array-like object.

Some of the benchmark code can be a little dense. Not *very* hard to
read but perhaps harder than it needs to be.
These changes (many of them whitespace-only) hopefully improve
readability.
There are also a few cases of `assert.equal()` that are changed to
`assert.strictEqual()`.

The depth benchmark for timers sets a timer that sets a timer that sets
a timer that... 500K of them.
Since each timer has to wait for the next tick of the event loop this
benchmark takes a very long time to run compared to the breadth
test that is already in the file. This may be more of an event loop
benchmark than a timer benchmark.
Reduce the number of iterations for the depth test as it's really just
running the iterations in sequence, not in parallel. And even on an
infinitely fast machine, it would take over 8 minutes to run because
each tick of the event loop would have to wait 1ms before firing the
timer.
Split the depth and breadth benchmarks so that their `N` values can be
set independently.
Do some minor refactoring to the benchmarks (but no ES6 additions so
that the benchmarks can still be run with old versions of Node.js).

In most cases, named functions match the variable or property to which

This change applies that rule to instances in the code base that don't
comply with that practice.
This will be enforceable with a lint rule once we upgrade to ESLint

This removes the need for parsing stdout from the benchmarks. If the

This also fixes the parsing of CLI arguments, by inferring the type

Only two benchmarks had to be changed:
* http/http_server_for_chunky_client.js this previously used a spawn
now it uses a fork and relays the messages using common.sendResult.
* misc/v8-bench.js this utilized that v8/benchmark/run.js called
global.print and reformatted the input. It now interfaces directly
with the benchmark runner global.BenchmarkSuite.
