This patch is NFC and cleans up `computeFeasibleUserVF()` by moving the clamping
into a separate function, that can be reused in multiple places, including
computeFeasibleMaxVF. This helps prepare the code to operate on scalable
VFs.

This patch is a preparatory patch with the ultimate goal of making
`computeMaxVF()` return both a max fixed VF and a max scalable VF,
so that `selectVectorizationFactor()` can pick the most cost-effective
vectorization factor.
