Emulator Issues #12332
Zen 3 is capable of using PDEP/PEXT without emulation through microcode
This PR shows that PDEP/PEXT is disabled for AMD Zen because it's not supported nativley.
This is not the case anymore according to the developer documenation for Zen3 processors:
"The AMD family 19h processor has native ALU support for PDEP/PEXT, so one such instruction can
be sustained per cycle, with a three-cycle latency for producing the result. Software that uses different
codepaths for processors with fast and slow PDEP/PEXT instructions should choose the fast
PDEP/PEXT codepath for family 19h processors." (Page 40, 2.10.2 Execution Units)

My question is did this PR also disable PDEP/PEXT for Zen3 family?
