Support for Pentium events was removed completely in e92a1350b5.
Don't bump .Dd where we are just removing xrefs.

The MEM_UOPS_RETIRED actually work the same way as the Sandy
Bridge counters, but the counters were documented in a different
way and that seemed to cause the Ivy Bridge counters to be
implemented incorrectly. Use the same counter definitions as
Sandy Bridge. While I'm here, rename the counters to match
what's documented in the datasheet.

On Sandy Bridge and later, to count branch-related events you
have to or together a mask indicating the type of branch
instruction to count (e.g. direct jump, branch, etc) and a bits
indicating whether to count taken and not-taken branches. The
current counter definitions where defining this bits individually,
so the counters never worked and always just counted 0.
Fix the counter definitions to instead contain the proper
combination of masks. Also update the man pages to reflect the
new counters.
