29e74d4952 benchmark: refactor for consistent style
Code in benchmark directory sometimes uses `function () {}` for
anonymous callbacks and sometimes uses `() => {}`. Multi-line arrays
sometimes have a trailing comma and sometimes do not. Update to always
use arrow functions for anonymous callbacks and trailing commas for
multiline arrays.

worker: remove --experimental-worker flag
Having an experimental feature behind a flag makes change
if we are expecting significant breaking changes to its API.

Since the Worker API has been essentially stable since
its initial introduction, and no noticeable doubt about
possibly not keeping the feature around has been voiced,
removing the flag and thereby reducing the barrier to experimentation,
and consequently receiving feedback on the implementation,
seems like a good idea.

1698fc96af benchmark: support more options in startup benchmark
1. Add options to benchmark the startup performance of a node
  "instance" after running a script. By default there are two options:
  `test/fixtures/semicolon` which is basically an empty file,
  and `benchmark/fixtures/require-cachable` which require all
  the cachable modules before exiting. This allows us to measure
  the overhead of bootstrap in more scenarios.
2. Add options to benchmark the overhead of spinning
  node through a process and through a worker.

benchmark: add common.binding()
Recently, process.binding() was replaced with internalBinding().
However, internalBinding() is not available on older builds of
Node, which are often used for benchmarking purposes. This commit
adds a common.binding() to the benchmarks to work around the
issue. Hopefully, this can be removed in the not too distant
future.

eb9748d222 async_hooks: add missing async_hooks destroys in AsyncReset
This adds missing async_hooks destroy calls for sockets (in
_http_agent.js) and HTTP parsers. We need to emit a destroy in
AsyncWrap#AsyncReset before assigning a new async_id when the instance
has already been in use and is being recycled, because in that case, we
have already emitted an init for the "old" async_id.

This also removes a duplicated init call for HTTP parser: Each time a
new parser was created, AsyncReset was being called via the C++ Parser
class constructor (super constructor AsyncWrap) and also via
Parser::Reinitialize.

e41ccd4e2d n-api: improve runtime perf of n-api func call
Added a new struct CallbackBundle to eliminate all
GetInternalField() calls.

The principle is to store all required data inside a C++ struct,
and then store the pointer in the JavaScript object. Before this
change, the required data are stored in the JavaScript object in
3 or 4 seperate pointers. For every napi fun call, 3 of them
have to be fetched out, which are 3 GetInternalField() calls;
after this change, the C++ struct will be directly fetched out
by using v8::External::Value(), which is faster.

Profiling data show that GetInternalField() is slow.
On an i7-4770K (3.50GHz) box, a C++ V8-binding fun call is 8 ns,
before this change, napi fun call is 36 ns; after this change,
napi fun call is 20 ns.

The above data are measured using a modified benchmark in
'benchmark/misc/function_call'. The modification adds an indicator
of the average time of a "chatty" napi fun call (max 50M runs).
This change will speed up chatty case 1.8x (overall), and will cut
down the delay of napi mechanism to approx. 0.5x.

Background: a simple C++ binding function (e.g. receiving little
from JS, doing little and returning little to JS) is called
'chatty' case for JS<-->C++ fun call routine.

This improvement also applies to getter/setter fun calls.

This also fixes the parsing of CLI arguments, by inferring the type

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.

c647e87504 lib: freelist: use .pop() for allocation
Array#pop() is known to be faster than Array#shift().
To be exact, it's O(1) vs. O(n). In this case there's no difference
from which side of the "pool" array the object is retrieved,
so .pop() should be preferred.

dcfda1007b tools,benchmark: increase lint compliance
In the hopes of soon having the benchmark code linted, this change
groups all the likely non-controversial lint-compliance changes such as
indentation, semi-colon usage, and single-vs.-double quotation marks.

Other lint rules may have subtle performance implications in the V8
currently shipped with Node.js. Those changes will require more careful
review and will be in a separate change.

36e8a2c63d node: improve performance of hrtime()
process.hrtime() was performing too many operations in C++ that could be
done faster in JS. Move those operations over by creating a length 4
Uint32Array and perform bitwise operations on the seconds so that it was
unnecessary for the native API to do any object creation or set any
fields.

This has improved performance from ~350 ns/op to ~65 ns/op. Light
benchmark included to demonstrate the performance change.
