This benchmark checks comparison with StringAt functions against
each other and and constants. The benchmarks will serve to measure
the effect of an optimization that will omit the implicit

As a clean-up, this also entirely removes the "second" field from n-ary

The `FAST_` prefix doesn’t make much sense — they’re all just different cases
with their own optimizations. Packedness being implicit (e.g. `FAST_ELEMENTS`
vs. `FAST_HOLEY_ELEMENTS`) is not ideal, either.
This patch renames the FAST elements kinds as follows:
- e.g. FAST_ELEMENTS => PACKED_ELEMENTS
- e.g. FAST_HOLEY_ELEMENTS => HOLEY_ELEMENTS
The following exceptions are left intact, for lack of a better name:
- FAST_SLOPPY_ARGUMENTS_ELEMENTS
- SLOW_SLOPPY_ARGUMENTS_ELEMENTS
- FAST_STRING_WRAPPER_ELEMENTS
- SLOW_STRING_WRAPPER_ELEMENTS
This makes it easier to reason about elements kinds, and less confusing to
explain how they’re used.

Functions that take mandatory parameters plus a number of optional
parameters, that need to be materialized as an Array are quite common.
The simplest possible case of this is essentially:
function foo(mandatory, ...args) { return args; }
Babel translates this to something like:
function foo(mandatory) {
"use strict";
for (var _len = arguments.length,
args = Array(_len > 1 ? _len - 1 : 0),
_key = 1; _key < _len; _key++) {
args[_key - 1] = arguments[_key];
}
return args;
}
The key to great performance here is to make sure that we don't
materialize the (unmapped) arguments object in this case, plus that we
have some kind of fast-path for the Array constructor and the
initialization loop.
This microbenchmark ensures that we have decent performance even in the
case where the assignment to args is polymorphic, i.e. the arguments
have seen different elements kinds, starting with FAST_HOLEY_ELEMENTS
and then FAST_HOLEY_SMI_ELEMENTS.

The results are unreliable as-is, because es5 and es6 run in the same d8
process consecutively. The graph also shows a huge amount of noise,
which seems to be mostly resolved with this change.

The graphs don't show any performance bump for
https://codereview.chromium.org/2659623002, which I do see a much better result for
locally. I suspect the function isn't being optimized in turbofan when the
benchmarks run. Maybe this warmup flag will trigger that.

These benchmarks are intended to compare the overhead of async-await vs.
a naive promise implementation vs. the babel async-await transformation.
The functions in the benchmark don't do any work themselves, so results
should reflect only overhead of the chosen implementation.
Current numbers on my local machine (higher is better):

Defining the subclass within the loop significantly affects subsequent
test results. For instance, the Search benchmark is 50% slower if the

Each benchmark is further split to measure fast and slow paths.

Add array pattern destructuring micro-benchmarks. These benchmarks compare
a naive ES5 immplementation to an ES6-style implementation that uses
destructuring.

This adds a common perf configuration for JSTests including
Classes, Collections, Iterators and Strings. This allows
the android test runner to handle subdirectories correctly
and to share the base.js resource in the parent directory.
The new json config has added resources configs for the
Android runner.
The perf runner's relative paths on the device are fixed as
well. Resources are only pushed on the configuration node
where they are specified. They are pushed to a dir on the
device that follows the same directory structure as on the
host. The binary is executed in the benchmark folder on the
device like on the host to allow relative path file
loading.

The big change here is to split out each key type into its own
benchmark suite, since optimizations for different key types
are likely to be disjoint. ForEach tests have also been split
into separate "Iteration" suites, again with the thought that
iteration performance is likely separable from key type.
As part of adding the new tests, rejiggered the existing tests:
- Map.set and Set.add (along with their Weak variants) no longer
include construction costs in their scores
- Moved key logic into the shared common.js
