Only print --report-optimized-on rmem fence info for non-fast ons
[reviewed by @mppf]
--report-optimized-on prints information about what on-clauses were
optimized to be fast-ons and whether remote memory fences were optimized
out. fast-ons require the rmem fence removal so there’s no need to print
the information twice in that case.
