Andreas Madsen f99471b2ae benchmark: refactor to use process.send
This removes the need for parsing stdout from the benchmarks. If the
process wasn't executed by fork, it will just print like it used to.

This also fixes the parsing of CLI arguments, by inferring the type
from the options object instead of the value content.

Only two benchmarks had to be changed:

* http/http_server_for_chunky_client.js this previously used a spawn
now it uses a fork and relays the messages using common.sendResult.

* misc/v8-bench.js this utilized that v8/benchmark/run.js called
global.print and reformatted the input. It now interfaces directly
with the benchmark runner global.BenchmarkSuite.

Zach Bjornson a1059afd39 buffer: speed up swap16/32, add swap64
* Speed up buffer.swap16 and swap32 by using builtins. Up to ~6x gain.
  Drop transition point between JS and C++ implementations accordingly.
  Amount of performance improvement not only depends on buffer size but
  also memory alignment.
* Fix tests: C++ impl tests were testing 0-filled buffers so were
  always passing.
* Add similar buffer.swap64 method.
* Make buffer-swap benchmark mirror JS impl.

doc/api/buffer.markdown has an entry of "added: REPLACEME" that should
be changed to the correct release number before tagged.

Because node is currently using a very old version of cpplint.py it
doesn't know that std::swap() has moved from <algorithm> to <utility> in
c++11. So until cpplint.py is updated simply NOLINT the line.
Technically it should be NOLINT(build/include_what_you_use), but that
puts the line over 80 characters causing another lint error.

Additionally, some changes to the benchmark runner are needed in
order for the included benchmark to be run correctly. Specifically,
the regexp used to parse `key=value` parameters contained a greedy
quantifier that was causing the `key` to match part of the `value`
if `value` contained an equals sign.

James M Snell 7d73e60f60 buffer: add swap16() and swap32() methods
Adds Buffer.prototype.swap16() and Buffer.prototype.swap32()
methods that mutate the Buffer instance in-place by swapping the
16-bit and 32-bit byte-order.

Example:

```js
const buf = Buffer([0x1, 0x2, 0x3, 0x4]);
buf.swap16();
console.log(buf);
  // prints Buffer(0x2, 0x1, 0x4, 0x3);

buf.swap32();
console.log(buf);
  // prints Buffer(0x3, 0x4, 0x1, 0x2);
```
