Make the inner loop execute fewer compare-and-branch executions per
processed byte, resulting in a 50% or more speedup.
This coincidentally fixes an out-of-bounds read:
while (unbase64(*src) < 0 && src < srcEnd)
Should have read:
while (src < srcEnd && unbase64(*src) < 0)
But this commit removes the offending code altogether.

This also changes the launch of clients to wait until all

Break up Buffer#toString() into a fast and slow path. The fast path
optimizes for zero-length buffers and no-arg method invocation.
The speedup for zero-length buffers is a satisfying 700%. The no-arg
toString() operation gets faster by about 13% for a one-byte buffer.
This change exploits the fact that most Buffer#toString() calls are
plain no-arg method calls. Rewriting the method to take no arguments
means a call doesn't go through an ArgumentsAdaptorTrampoline stack
frame in the common case.

Buffer.byteLength is important for speed because it is called whenever a
new Buffer is created from a string.
This commit optimizes Buffer.byteLength execution by:
- moving base64 length calculation into JS-land, which is now much
faster
- remove redundant code and streamline the UTF8 length calculation
It also adds a benchmark and better tests.

This commit fixes a few things for this benchmark:
1. Ensures the temporary directory for the unix socket exists.
2. Prevents the client code from being run directly because the
server script is the one that calls out the client code.
3. Ensures the server is closed once the client benchmarks have
finished.
4. Since this is an http benchmark, it should be moved to the http
benchmarks subdirectory.

This commit adds an `OUTPUT_FORMAT` environment variable option for
all benchmark tests that allow either 'csv' or 'default' output. Default
output has been left unchanged, and csv output prints out the csv
headers along with the csv formatted per-test output, each test also
seperated by a newline.
It can be used like the following:
$ OUTPUT_FORMAT=csv iojs benchmark/common.js http
Not specifying the OUTPUT_FORMAT env var will default to 'default'.
Specifying a bad value will throw an error.

This commit adds a graphing script (in R) for graphing the CSV output
of a benchmark. It can be run like this:
```
$ OUTPUT_FORMAT=csv iojs benchmark/http/client-request-body.js >

$ ./benchmark/plot_csv.R data.csv graph.png bytes type
```
This will graph the output to `graph.png`, using the output's `bytes`
value as X and the result value for each as Y. Output will be grouped
by `type`.
Running as the example yields a beautiful graph like this:

The reason behind this is that its totally pointless (the lines don't

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.

Force V8 to optimize url.parse() before starting the actual benchmark.
Tries to minimize variance between successive runs caused by the
optimizer kicking in at different points.
It does not seem to have much impact, CPU times are roughly the same
before and afterwards; url.parse() quickly plateaus at a local optimum
where most time is spent in V8 builtins, notably Runtime_StringSplit()
and Object::GetElementWithReceiver() calls originating from
deps/v8/src/uri.js, with no recurring optimize/deoptimize cycles that
I could spot.
Still, I don't see any downsides to pre-optimizing the function being
benchmarked so in it goes.
