As with the inter loop filter, performance metrics seem to be biased in
favour of the C implementation because checkasm inputs almost always
fall in the no-op case.

After the branch, the expected SEW/LMUL ratio is 1 byte/vector.
So we have to set the same ratio before branching (QEMU does not care,

lavc/riscv: depend on RVB and simplify accordingly
...
There is no known (real) hardware with V and without the complete B
extension. B was indeed required in the RISC-V application profile from
2022, earlier than V. There should not be any relevant hardware in the
future either.
In practice, different R-V Vector optimisations in FFmpeg already depend on
every constituent of the B extension anyhow, so it would not work well.
