Integer types have a `count_ones` method that end up calling `intrinsics::ctpop`. On some architectures, that intrinsic is translated as a corresponding CPU instruction know as "popcount" or "popcnt". This PR makes it so that searching for those names in rustdoc shows those methods. CC https://blog.rust-lang.org/2020/11/19/Rust-1.48.html#adding-search-aliases
