b62343d83c benchmark: add default configs to buffer benchmark
Add default values to use for `type` and `method` in `buffer` benchmarks
when the provided configuration value is an empty string. This is
primarily useful for testing, so the test can request a single iteration
without having to worry about providing different valid values for the
different benchmarks.

While making this change, some `var` instances in immediately
surrounding code were changed to `const`. In some cases, `var` had been
preserved so that the benchmarks would continue to run in versions of
Node.js prior to 4.0.0. However, now that `const` has been introduced
into the benchmark `common` module, the benchmarks will no longer run
with those versions of Node.js anyway.

68ba9aa0fb test,lib,benchmark: match function names
In most cases, named functions match the variable or property to which
they are being assigned. That also seems to be the practice in a series
of PRs currently being evaluated that name currently-anonymous
functions.

This change applies that rule to instances in the code base that don't
comply with that practice.

This will be enforceable with a lint rule once we upgrade to ESLint
3.8.0.

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.

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);
```
