Rewrite add/sub_bitmaps() assembly
Change list:
- No special handling of unaligned case (removed in previous commit).
- Common macro for both add_bitmaps() and sub_bitmaps().
- Reduced register usage and efficient 32-bit version.
- add_bitmaps() no longer rely on zero padding.
- Vectorized handling of width tails (instead of byte loop
in sub_bitmaps(), great speedup for non-empty tails).
