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.
