Subject: [PATCH] cmov: mark `isize`/`usize` impls of `Cmov(Eq)` as always
 available

Via rustc itself:

    expected values for `target_pointer_width` are: `16`, `32`, and `64`

This adds a `doc(cfg(true))` attribute to the impls for `isize` and
`usize` to hide the `cfg` gating so it doesn't show up in the rustdoc,
but it's still retained to the crate compiles if rustc suddenly decides
to add support for e.g. `8` or `128`-bit wide pointers.
