This commit uses separate functions to isolate deopts caused by
try-catches and avoids fn.apply() for callbacks with small numbers
of arguments.
These changes improve performance by ~1-40% in the various
nextTick benchmarks.

By limiting property getting/setting to only where they are
absolutely necessary, we can achieve greater performance
especially with small utf8 inputs and any size base64 inputs.

deps/v8/benchmarks/regexp.js clobbers the RegExp global, breaking
util.format() and console.log(). Unclobber it to keep the other
benchmarks working.
Fixes the following error when running benchmark/misc/v8-bench.js:
$ out/Release/iojs benchmark/misc/v8-bench.js
util.js:84
if (new RegExp('\\b' + set + '\\b', 'i').test(debugEnviron)) {

This could alternatively be addressed by caching the RegExp global
in lib/util.js. That's not a bad approach and I considered it but
doing it for just RegExp and not other globals would be half-baked.
Maybe the more thorough approach where we cache all globals at
start-up is something for a follow-up pull request.

The copyright and license notice is already in the LICENSE file. There
is no justifiable reason to also require that it be included in every
file, since the individual files are not individually distributed except
as part of the entire package.
Adds the feature to define arguments for the function called in
domain.run(), this is supposed to be useful when a function is called from
another context and some values from the current context are needed as
arguments, it's similar to the callback from setTimeout or setInterval.

For throughput benchmarks, run with just 5s durations rather than 1s and 3s.
For startup benchmark, run with just a single 1s duration, since it's very
consistent anyway.
