Research direction

Start by reviewing the cpufeatures crate and its documentation for how existing ARM instruction-set support is detected. Determine the appropriate representation of NEON support and verify the behavior on ARM targets; done means callers can reliably detect NEON support as they can for the crate’s existing features.

Written by the indexing model from the issue text.

Description

It would be useful to be able to detect support for the neon instruction set on ARM, allowing to use vectorised instructions. As far as I can tell from the documentation, this is not yet supported.
