Simon Sapin f365de353a Add popcount and popcnt as doc aliases for count_ones methods.
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.
