Auto merge of #120370 - x17jiri:likely_unlikely_fix, r=saethlin
Likely unlikely fix

RFC 1131 ( https://github.com/rust-lang/rust/issues/26179 ) added likely/unlikely intrinsics, but they have been broken for a while: https://github.com/rust-lang/rust/issues/96276 , https://github.com/rust-lang/rust/issues/96275 , https://github.com/rust-lang/rust/issues/88767 . This PR tries to fix them.

Changes:
- added a new `cold_path()` intrinsic
- `likely()` and `unlikely()` changed to regular functions implemented using `cold_path()`
