Comment:
I built this PR on a Zen 3 CPU and ran a test that built a sparse finite-element matrix and then used SuperLU to performan LU factorization. Although the SuperLU performance won't change, the setup does some heavy looping in Python and the overall time for the routine dropped from 2.78 sec to 2.3 sec, each trial averaged over several runs. I installed the Zen-built package on another system with a 9th-generation Intel CPU and re-ran the same test, with the times dropping from 3.7 sec to 2.75 sec.

It seems these optimizations offer tangible benefits, and they translate to different systems.
