This constructs different typed arrays from different types of other
typed arrays, hopefully countering microbenchmarks which are able to
optimize for exactly one pair of types.

Add a simple benchmark for a TypedArray constructor. Run once with the
default pipeline and once with turbofan so that we can compare the
performance.
Also fixes a typo in the Regex for the result of the CopyWithin
benchmark which stopped the results showing up in the perf
dashboard.

The graphs don't show any performance bump for

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.

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
