Add ability to time simplifyTemplates.

Not-specific to this commit, but it's error prone that a simple timer output requires code to be duplicated.
Something like

{
            Timer t("Tokenizer::tokenize::simplifyTemplates", mSettings->showtime, mTimerResults), mTimerResults;
            simplifyTemplates();
 }

would be better imho.

I just did a cut and paste. I didn't even look at what Timer does. I just assumed it was written that way because Timer has high overhead (doesn't have a no-op mode).

What you propose makes sense if Timer has no overhead when not enabled.
