Description
Summary
The current unused variable pass does not check variables inside the template function.

#[lang = "sized"]
pub trait Sized {}
fn test<T> (a: usize) -> () {
}

Research direction
Start by tracing the unused variable pass and how it handles the generic function in the reproducer. Run the provided Rust example to confirm that the unused parameter a is not reported. Done means the pass also checks variables inside template functions and the reproducer produces the expected unused-variable diagnostic.
