[benchmark] Adds native call benchmark.

Adds new benchmarks for native calls, parallel to the
existing benchmark for FFI calls.

This makes it possible (with some caveats) to compare
overheads of calling through native and FFI.

Local results on Linux, x64, AOT (for reference):

NativeCall.Uint8x01(RunTime): 585.9797891036907 us.
NativeCall.Int64x20(RunTime): 1340.2451440053583 us.
NativeCall.Doublex01(RunTime): 694.4875 us.
NativeCall.Doublex20(RunTime): 1610.102172164119 us.

NativeCall.Handlex20(RunTime): 836.6783772480134 us.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
