This change includes the following: * Decision to use subtype range checks is revised to work regardless of the NNBD mode. * Handling of dynamic/Object/void is removed from SlowTypeTest stub as we use TopTypeTypeTest stub for the top types. That handling was unnecessary but harmless. However, in NNBD strong mode it becomes incorrect for non-nullable Object. * TypeTestingStubGenerator::OptimizedCodeForType now falls back to TypeTestingStubGenerator::DefaultCodeForType instead of directly using StubCode::DefaultTypeTest(). This refactoring is needed to avoid duplicating a more complicated logic in TypeTestingStubGenerator::DefaultCodeForType in the future.

Dart VM Compilation Pipeline
This folder contains Dart VM compilation pipeline.
Compilation pipeline is mainly responsible for converting AST or Kernel AST into IL flow graphs and then generating native code from IL.
It has the following structure:
| Directory | What goes there |
|---|---|
assembler/ |
Assemblers and disassemblers |
backend/ |
IL based compilation backend: optimization passes and architecture specific code generation rules |
frontend/ |
Frontends responsible for converting AST into IL |
jit/ |
JIT specific passes and compilation pipeline entry points |
aot/ |
AOT specific passes and compilation pipeline entry points |
. |
Shared code or code without clear designation. |
Currently there are no layering restrictions and components from different subfolders can reference each other.
