Add Zen 3 support #15

Closed wolfpld closed 3 years ago

wolfpld commented 3 years ago

This PR adds support for Zen 3 uarch. There is very little documentation available right now, so this PR assumes that performance counters haven't been changed since Zen 2.

Notably, there are new FP execution pipes (4, 5), which are not handled in this PR.
