Some of these are justified, mainly convert_up/convert_down/mask_equal/equal not being implemented for some extensions

But others aren't:

• convert_down doesn't make sense for uint_8 (no smaller type exists)
• convert_up doesn't make sense for uint64_t (no larger type exists)
• shift_*** does not make sense for float or double (C++ scalars and AVX don't supports that, neither should we. User should cast instead.)
• there are probably more cases that just don't occur because the corresponding primitive doesn't have tests yet, e.g.
  cast

I see three ways to deal with this:

1. Get rid of this warning entirely
2. Only emit the warning if the implementation is missing because of lscpu flags, not for implementations that were never written at all
3. Add a yaml tag (e.g. implementation_omitted) to indicate implementations that are explicitly not desired.

My personal favorite is 3., since i would rather not remove a warning that is very helpful in development.
While we're at it, we might consider emitting different warnings for the two cases of

• missing because of lscpu flags
• missing because no implementation was written

Which mean very different things for the developer.
