With the arrival of generic structs (https://chromium-review.googlesource.com/c/v8/v8/+/1714868) the existing type inference procedure for generic calls became incomplete, since it could not infer types that were only constrained as part of generic types. For instance, given struct Box<T: Type> { ... } macro unbox<T: type>(box: Box<T>): T the type argument (Smi) at the following call site const box: Box<Smi> = ...; unbox(box); could not be inferred. This CL re-implements the inference procedure and documents the semantics of type argument inference in Torque a bit more clearly.
