Scott Wolchok 2d885ab73d [jit] Reduce refcounting of Types (#65345) ... Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/65345 FooType::get() can return a const reference. Inconveniently, converting shared_ptr<FooType> to shared_ptr<Type> requires a copy & refcount bump, so to properly take advantage of this in unshapedType() we need to take a const Type& in isSubtypeOf(), which is good practice anyway -- don't require a shared_ptr if you don't need to take ownership. ghstack-source-id: 140044165 Test Plan: CI perf says c10::unshapedType time decreased from 2.8% to 2.2% during static runtime startup, though I expect this to be generally beneficial.
