Regression test for https://go.dev/issue/76287:
ensure that inlining a function that wraps go1.26's new(expr)
correctly inserts a conversion as needed, just as it would for a
declared generic function equivalent to 'new'.

- f uses a declared _new(expr) function.
- g uses the built-in new(expr) function.
