[Test] Add TypedArray constructor benchmarks.

Browse Source 
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.
