neon variance: add small missing sizes

Some of the mixed sizes were missing. They can be implemented trivially
using the existing helper function.

When comparing the previous 16x8 and 8x16 implementations, the helper
function is about 10% faster than the 16x8 version. The 8x16 is very
close, but the existing version appears to be faster.
