Required inputs: IR

A std::shared_ptr shall be passed to a function as:

1. a copy to express the function shares ownership an lvalue reference to express that the function replaces the managed object
2. a const lvalue reference to express that the function retains a reference count.
A std::unique_ptr shall be passed to a function as:
1. a copy to express the function assumes ownership
2. an lvalue reference to express that the function replaces the managed object.
