6c6e9a45ff 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();
  }

966ab1ec5e finally, maintain a global list of timer groups, allowing us to 
implement TimerGroup::printAll, which prints and resets all active
timers.

2a254fd348 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.

7e3957a646 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

0c8d8cd921 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.

226e1d8bda 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.

a08868acb3 Append to the ActiveTimers std::vector before looking at the timer instead 
of after, so that any reallocation it does doesn't get counted for the pass
being timed.  This probably doesn't account for a timing discrepancy I was
looking into, but I'm fixing it anyway.

f1a9655358 Don't print a 'Total Execution Time' line for the 'Miscellaneous Ungrouped

298690bde2 Fix a bug that made the nightly tester *really* slow. During changes for 
portability, the --track-space option was inadvertently ignored. This patch
fixes that so that sys::Process::GetMallocUsage() is only invoked if the
--track-spaces option is given. Apparently the mallinfo() call that
GetMallocUsage() uses is *very* slow, especially when processing very large
modules like projects/llvm-test/MultiSource/Applications/kimwitu++.
