  lavu/riscv: remove bogus B extension
  
  The B Bit manipulation extension was not defined to this day, and
  probably never will. Instead it was broken down into Zba, Zbb, Zbc and
  Zbs with no particular blessed set to make up B.
  
  This removes the bogus field test. Linux never set this bit, nor
  (AFAICT) did FreeBSD or any other OS. We can always add it back in the
  unlikely event that it gets taken into use.

  lavc/vp8dsp: restrict RVI optimisations
  
  They are actually awfully slow if the CPU does not support misaligned
  accesses natively, so only use them if misaligned accesses are fast.
