Reapply "[vm/compiler] Pass arguments in registers" This reverts commit 63179aa49d666c2e347e29e7f77d43f1e777a900. See commit 1ab083ae487af531d1e28fb8fd6d50fb71aaadf9 for the original description of the change. The original change was reverted because it did not take into account that in Dart it is legal to make some parameters optional when you override a method. Such parameters should not be passed in registers - which means for each possible interface target we need to compute the minimum number of direct parameters accepted by all overrides. I have also added two comprehensive tests for different combinations of direct, optional and named parameters.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
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).
Dart is free and open source.
