Make FreeList faster by using Reflect.apply and not using
is_reused_symbol, but rather just checking whether any
items are present in the list prior to calling alloc.

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.

* Give createBenchmark and the Benchmark constructor
a third argument for specifying the command line flags
that this benchmark should be run with.
The benchmarks are no longer run with --expose-internals
by default, they will need to explicitly pass the flags.
* Rename options to configs in createBenchmark and the Benchmark
constructor to match the documentation since they are not optional.
* Comment the properties of a Benchmark object
Also improve the documentation about creating benchmarks
* Add detailed description of the arguments of `createBenchmark`
* Describe the two passes of running the benchmarks
* Suggest what kind of code should go where in the benchmark example

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.
