  Bit manipulation extension[1] is finishing the public review and waiting for
the rest of the ratification process, I believe that will become a ratified
extension soon, so I think it's time to submit to upstream for review now :)

As the title included RFC, it's not a rush to merge to trunk yet, I would
like to merge that until it is officially ratified.

This patch set is the implementation of bit-manipulation extension, which
includes zba, zbb, zbc and zbs extension, but only included in instruction/md
pattern only, no intrinsic function implementation.

Most work is done by Jim Willson and many other contributors
on https://github.com/riscv-collab/riscv-gcc.
