60% faster setImmediate with 0 args (15% if self-recursive)
4x faster setImmediate with 1-3 args, 2x with > 3

`setTimeout()`, `setInterval()` and `setIntermediate` currently
throw errors when receiving non-function objects as their first
argument, but only do so when trying to execute the callback,
i.e. after the waited time has passed. This may complicate
debugging when a lot of calls to `setTimeout()`/etc. are involved,
so failing as early as possible seems like a good idea.
`setTimeout()` historically ignored an falsy first
argument, while the other functions do not and throw instead.
This patch changes this behaviour to make all three match and
adds remarks in the corresponding documentation.

Before this change, _unrefActive would keep the unrefList sorted when
adding a new timer.
Because _unrefActive is called extremely frequently, this linear scan
(O(n) at worse) would make _unrefActive show high in the list of
contributors when profiling CPU usage.
This commit changes _unrefActive so that it doesn't try to keep the
unrefList sorted. The insertion thus happens in constant time.
However, when a timer expires, unrefTimeout has to go through the whole
unrefList because it's not ordered anymore.
It is usually not large enough to have a significant impact on
performance because:
- Most of the time, the timers will be removed before unrefTimeout is
called because their users (sockets mainly) cancel them when an I/O
operation takes place.
- If they're not, it means that some I/O took a long time to happen, and
the initiator of subsequents I/O operations that would add more timers
has to wait for them to complete.
With this change, _unrefActive does not show as a significant
contributor in CPU profiling reports anymore.
