This unifies the set/clear/test bit functions of asm/bitops.h.
I have not attempted to merge the bit-finding functions, since they
rely on the machine word size and can't be easily restructured to work
generically without a lot of #ifdefs. In particular, the 64-bit code
can assume the presence of conditional move instructions, whereas
32-bit needs to be more careful.
The inline assembly for the bit operations has been changed to remove
explicit sizing hints on the instructions, so the assembler will pick
the appropriate instruction forms depending on the architecture and
the context.
