In this PR I added the detection of rep instructions:

  • Fast Short REP MOV
  • Fast zero-length REP MOVSB
  • Fast short REP STOSB
  • Fast short REP CMPSB/SCASB

Note:
I didn't find cpuid dump with REP MOVSB and REP CMPSB/SCASB only added alder lake where we have Fast short REP STOSB/ Fast Short REP MOV
