bug: implicit `*void` -> `*T` casting does not occur in function arguments

[thetayloredman]

Before we begin...

• I have updated the Zirco toolchain to the latest version
• I have searched the issue tracker for duplicates

What happened?

$ zrc - << EOF
struct S { x: i32 }
fn f(x: S);
fn main() -> i32 {
    f(0 as *void);
    return 0;
}
EOF
[E3010] Error: expected `struct { x: i32 }` for argument `0`, got `*struct {}`

What version of Zirco are you running?

HEAD

How can this bug be reproduced?

See above.

What behavior did you expect?

The code should compile.

What actually happened?

The code does not compile, and prints an error message.
Additionally, that error message lacks labels.

Other Context

Workaround: Just write the cast yourself.
