Rewrite BN_rshift()
This improves readability and eliminates special handling for various
cases, making the code cleaner and closer to constant time.
Basic benchmarking shows a performance gain on modern 64 bit architectures,
while there is a decrease on legacy 32 bit architectures (i386),
particularly for the zero bit shift case (which is now handled in the
same code path).
