I've left it as is for now due to the lack of a motivating example and to keep
it consistent with `getMinSVEVectorSizeInBits`/`getMinSVEVectorSizeInBits`,
which I suppose could return 128/2048 as the architecture bounds and avoid this
problem altogether. Please let me know if you'd rather I add it.
I'll let the tests run and assuming they are OK merge it.
