Following the results of the previous comparison, i've used Jorge's
profiling example on the 'call_method' bench for trusty stock, no LTO,
no PGO and Xenial stock, no PGO and no LTO. Here are the results. Notice
the difference between Trusty Stock & Trusty nopgo, as opposed to the
execution profiles of the other tests.
Trusty Stock
