bors 380addd7d2 Auto merge of #100733 - scottmcm:inline-from-from-identity, r=m-ou-se 
Inline `<T as From<T>>::from`

I noticed (in https://github.com/rust-lang/rust/pull/100693#issuecomment-1218520141) that the MIR for <https://play.rust-lang.org/?version=nightly&mode=release&edition=2021&gist=67097e0494363ee27421a4e3bdfaf513> has inlined most stuff
```
scope 5 (inlined <Result<i32, u32> as Try>::branch)
```
```
scope 8 (inlined <Result<i32, u32> as Try>::from_output)
```

But yet the do-nothing `from` call was still there:
```
_17 = <u32 as From<u32>>::from(move _18) -> bb9;
```

So let's give this a try and see what perf has to say.
