New wi::bitreverse function.
This patch provides a wide-int implementation of bitreverse, that
implements both of Richard Sandiford's suggestions from the review at
https://gcc.gnu.org/pipermail/gcc-patches/2023-May/618215.html of an
improved API (as a stand-alone function matching the bswap refactoring),
and an implementation that works with any bit-width precision.
