-DPERL_TRACE_OPS to produce reports on executed OP counts
This produces a report on the number of OPs of a given type that were
executed at the end of a program run. This can be useful in multiple
ways. One, it can help determine hotspots for optimization (yes, I know
execution count is not equal execution time). It can also help with
determining whether a given change to perl has had the desired effect on
deterministic programs.
