Auto merge of #25159 - inrustwetrust:wrapping_inline, r=alexcrichton

This was causing function calls to be emitted for bitwise complements, even with optimizations on.
Steps to reproduce:
```
$ cat wrapping.rs
fn main() {
    let a = std::num::Wrapping(std::env::args().len() as u32);
    let b = !a;
    println!("{}", b.0);
}
$ rustc -O wrapping.rs --emit=asm,link
$ grep Not wrapping.s
        callq   _ZN3num8wrapping23Wrapping$LT$u32$GT$.Not3not20hba4b266232e02b1dHkbE
