btver2 uops yaml file

When the attached uops yaml file is processed it reports a warning:

no exegesis target for x86_64-pc-windows-msvc, using default
Parsed 3 benchmark points
Printing analysis clusters results to file 'uop-clusters.csv'
Printing sched class consistency analysis results to file
'uop-inconsistencies.html'
expected ProcResIdx key, got JFPU0
expected ProcResIdx key, got JFPU0

And the results file indicates a mismatch from the schedule class, but removing
any one of the instructions makes the warning and the mismatch go away.
