[vm] Unify type testing stub testing framework. In particular, make it so that the type testing stub testing framework can use the same indirect stub call generation as the flow graph compiler. This avoids having to change generation in two places if we later update how indirect calls are generated. Other changes: * Generate a register mask of modified registers instead of a boolean for more precise reporting of what was modified. * Add a STCInternalRegs struct, like TTSInternalRegs, which exposes the registers not preserved by the subtype test cache stubs. * Be more precise in the TypeTestABI about which registers are preserved on successful checks (namely, the inputs provided by AssertAssignable and InstanceOf) and which may not be, and add the TTS and STC internal registers to the non-preserved list. TEST=Ran modified test on trybots for each supported architecture.

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).
Dart is free and open source.
