asm_goto_with_outputs

The tracking issue for this feature is: #119364

This feature allows label operands to be used together with output operands.

Example:

unsafe {
    let a: usize;
    asm!(
        "mov {}, 1"
        "jmp {}",
        out(reg) a,
        label {
            println!("Jumped from asm {}!", a);
        }
    );
}

The output operands are assigned before the label blocks are executed.
