  [RISCV] Remove BREV8 and ORC_B from hasAllNBitUsers in RISCVOptWInstrs. (#147830)

These instructions operate on bytes so we need to round the demanded
bits up to the nearest byte which we aren't doing. I think we forgot to
update this when we changed from hasAllWUsers to hasNBitUsers.

We don't have any test case for these instruction so remove them until
we can put together a test.
