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
