Subject: [PATCH] PerfCounters: don't exit on AMD ThreadRipper 3960X
Patch from
https://github.com/mozilla/rr/issues/2034#issuecomment-581769936
It's unclear whether this will actually make it work - the main issue
seems to be that some complex tests are failing, but people are
reporting that the debugger still works for some cases.
