Apply the same fix as in https://dart-review.googlesource.com/c/sdk/+/136709 to TypeArguments::CanShareInstantiatorTypeArguments and to TypeArguments::CanShareFunctionTypeArguments. Move the inlined code performing an instantiation cache lookup to stubs in order to reduce code size. Add stubs checking nullability of type arguments to share instantiator (or function) type arguments before looking up instantiation cache, and possibly calling into the runtime for instantiation. Modify constant propagator to instantiate constant type arguments at compile time.

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.
