bswap: make generic implementation more compiler-friendly
...
With these changes, gcc 4.5 and later recognise it as a bswap
and use the proper instructions on ARM and x86. On x86, the
16-bit bswap is recognised from gcc 4.1.

...
This reduces the number of false dependencies on header files and
speeds up compilation.
