Auto merge of #51171 - faern:const-bswap-ctpop-cttz-ctlz, r=oli-obk
Make some std::intrinsics `const fn`s Making some rustc intrinsics (`ctpop`, `cttz`, `ctlz` and `bswap`) `const fn`s. This is a pre-step to being able to make `swap_bytes`, `to_be` and `from_be` constant functions. That in itself could be ergonomic and useful. But even better is that it would allow `Ipv4Addr::new` etc becoming `const fn`s as well. Which might be really useful since I find it quite common to want to define them as constants. r? @oli-obk
