When there're missing arguments in a function call, present a list of
all the expected types:
```rust
fn main() {
t("");
}
fn t(a: &str, x: String) {}
```
```bash
% rustc file.rs
file.rs:3:5: 2:8 error: this function takes 2 parameters but 0
parameters were supplied [E0061]
file.rs:3 t();
^~~
file.rs:3:5: 2:8 help: run `rustc --explain E0061` to see a detailed explanation
file.rs:3:5: 2:8 note: the following parameter types were expected: &str, std::string::String
error: aborting due to previous error
```
