I appreciate the thought, but changing it from just counting the number of times
'volatile' shows up to, essentially, putting a minimum on the number of times
'volatile load' shows up is not a huge improvement.  Would you mind
further improving this test to (1) actually match the operands and (2) do the
negative testing for the lines which we expect to produce non-volatile loads?

John.
