I fixed a couple of things:

+ sumWasExecuted has an source code alignment issue
+ setWasExecuted comments said "iterate". I think you meant increments
+ be careful to keep spaces inside parentheses like code around it.  Same
  on both sides of both parentheses.

You can use mkChangeLogList to help write a ChangeLog formatted entry.  This
script is in the rtems-testing tree and is run from a directory with a
ChangeLog file in it.  The entry I committed with is in the ChangeLog file.

Do you think the branch taken/not taken booleans should be counters also?  We
are focused on gcov but branch path counts should be needed by gprof for
feedback on which paths to favor in optimization.

If you want to turn those into counters, we can use the same PR or you can open
another to do it.  If you want to use another, close this one.
