                                      TuningBranchFusion,
+                                     TuningFastScalarFSQRT,
                                      TuningFastScalarShiftMasks,
----------------
Please also add `TuningFastVectorFSQRT`, i don't see any difference between scalar and vector variants at least on znver3.
