Force V8 to optimize url.parse() before starting the actual benchmark.
Tries to minimize variance between successive runs caused by the
optimizer kicking in at different points.
It does not seem to have much impact, CPU times are roughly the same
before and afterwards; url.parse() quickly plateaus at a local optimum
where most time is spent in V8 builtins, notably Runtime_StringSplit()
and Object::GetElementWithReceiver() calls originating from
deps/v8/src/uri.js, with no recurring optimize/deoptimize cycles that
I could spot.
Still, I don't see any downsides to pre-optimizing the function being
benchmarked so in it goes.

Remove the 'gc' event from the v8 module and remove the supporting
infrastructure from src/. It gets the axe because:
1. There are currently no users. It was originally conceived as
an upstreamed subset of StrongLoop's strong-agent GC metrics,
but the strong-agent code base has evolved considerably since
that time and has no use anymore for what is in core.
2. The implementation is not quite sound. It calls into JS land
from inside the GC epilog and that is unsafe. We could fix
that by delaying the callback until a safe time but because
there are no users anyway, removing it is all around easier.

In cases where many small writes are made to a stream
lacking _writev, the array data structure backing the
WriteReq buffer would greatly increase GC pressure.
Specifically, in the fs.WriteStream case, the
clearBuffer routine would only clear a single WriteReq
from the buffer before exiting, but would cause the
entire backing array to be GC'd. Switching to [].shift
lessened pressure, but still the bulk of the time was
spent in memcpy.
This replaces that structure with a linked list-backed
queue so that adding and removing from the queue is O(1).
In the _writev case, collecting the buffer requires an
O(N) loop over the buffer, but that was already being
performed to collect callbacks, so slowdown should be
neglible.

Fixes the following assertion on slow systems, like our ARM buildbot:
$ out/Debug/node test/simple/test-timers-unref.js

node::AsyncWrap::MakeCallback(uint32_t, int,
v8::Handle<v8::Value>*): Assertion `cb_v->IsFunction()' failed.
Aborted
The reason it only manifests on slow systems is that the test starts
a 1 ms interval timer, then defers timer.unref.bind({}) to the next
tick. On fast systems, the test completes in under a millisecond,
before the callback is called.
This commit makes timer.unref() check that the receiver actually has
a timeout callback property.

Seen with g++ 4.9.2 on x86_64 Linux: a SIGSEGV is generated when the
input to v8::String::NewFromTwoByte() is not suitably aligned.
g++ 4.9.2 emits SSE instructions for copy loops. That requires aligned
input but that was something StringBytes::Encode() did not enforce until
now. Make a properly aligned copy before handing off the input to V8.
We could, as an optimization, check that the pointer is aligned on a
two-byte boundary but that is technically still UB; pointers-to-char
are allowed to alias other pointers but the reverse is not true:
a pointer-to-uint16_t that aliases a pointer-to-char is in violation
of the pointer aliasing rules.
