Using arch::ignore_intersection causes shader compilation to fail

[Steelbirdy]

Expected Behaviour

Shader crate successfully compiles

Example & Steps To Reproduce

#[spirv(any_hit)]
pub fn my_any_hit() {
    let p = Vec3A::ZERO;
    if p.length_squared() < 1e-3 {
        unsafe { spirv_std::arch::ignore_intersection(); }
    }
}

1. Use the above snippet in a shader crate
2. Compilation fails

Replacing this with the below snippet causes it to compile.

#[spirv(any_hit)]
pub fn my_any_hit() {
    let p = Vec3A::ZERO;
    if p.length_squared() < 1e-3 {
        my_ignore_intersection();
    }
}

#[inline(never)]
fn my_ignore_intersection() {
    unsafe { spirv_std::arch::ignore_intersection(); }
}
