03c3dc7b68 Give NamedRegionTimer an Enabled flag, allowing all its clients to 
switch from this:

  if (TimePassesIsEnabled) {
    NamedRegionTimer T(Name, GroupName);
    do_something();
  } else {
    do_something(); // duplicate the code, this time without a timer!
  }

to this:

  {
    NamedRegionTimer T(Name, GroupName, TimePassesIsEnabled);
    do_something();
  }

83fa78efb1 finally, maintain a global list of timer groups, allowing us to 
implement TimerGroup::printAll, which prints and resets all active
timers.

b9312690a2 change TimerGroup to keep a linked list of active timers 
instead of just a count of them, and refactor the guts of
report printing out of removeTimer into its own method.
Refactor addTimerToPrint away.

fc86c3cfd6 remove support for per-time peak memory tracking, this 
isn't used by anyone and is better exposed as a non-per-timer 
thing.  Also, stop including System/Mutex.h in Timer.h

0ea86bc411 various timer fixes: move operator= out of line, 
eliminate the per-timer lock (timers should be 
externally locked if needed), the info-output-stream
can never be dbgs(), so drop the check.  Make some
stuff private.

46d9a64944 Make timers threadsafe again. This isn't quite as nice as I'd hoped (it uses locking rather than atomic arithmetic), 
but should work on all the platforms we care about.

I might revisit this if a totally awesome way to do it occurs to me.
