isaacs db5d58e842 bench: Use environ to run compares more than once 
This will run the benchmarks the number of times specified by NODE_BENCH_RUNS,
to attempt to reduce variability.

If the number of runs is high enough, it'll also throw out the top and bottom
quartiles, since that's where the outliers will be.

It's not very fancy statistics-fu, but it's better than nothing.

Also, linted this file.  It had tabs in it.  TABS!

isaacs e4383c0170 bench: Add flag to be silent in runner 
This is helpful in tracking down bailouts and deopts in Stream classes,
without triggering one from the string write in console.log

isaacs 4b80f217cd bench: Simplify duration arguments to benchmarks 
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.

isaacs 8476aefc8e fs: Change default WriteStream config, increase perf 
This increases fs.WriteStream throughput dramatically by removing the
"higher default water marks" for fs.WriteStream.

Also includes a benchmark.  Current performance is significantly higher
than v0.8 for strings at all tested levels except size=1.  Buffer
performance is still lackluster.

Further improvement in the stream.Writable base class is required, but
this is a start.

Trevor Norris 22b84e6216 buffer: floating point read/write improvements 
Improvements:
* floating point operations are approx 4x's faster
* Now write quiet NaN's
* all read/write on floating point now done in C, so no more need for
  lib/buffer_ieee754.js
* float values have more accurate min/max value checks
* add additional benchmarks for buffers read/write
* created benchmark/_bench_timer.js which is a simple library that
  can be included into any benchmark and provides an intelligent tracker
  for sync and async tests
* add benchmarks for DataView set methods
* add checks and tests to make sure offset is greater than 0
