Currently the ARM SVE helper code defines locally some utility functions for swapping 16-bit halfwords within 32-bit or 64-bit values and for swapping 32-bit words within 64-bit values, parallel to the byte-swapping bswap16/32/64 functions. We want these also for the ARM MVE code, and they're potentially generally useful for other targets, so move them to bitops.h. (We don't put them in bswap.h with the bswap* functions because they are implemented in terms of the rotate operations also defined in bitops.h, and including bitops.h from bswap.h seems better avoided.)
