a37a95ea2f One MDNode may be used to create regular DIE as well as abstract DIE. 
Keep track of abstract subprogram DIEs.

6e681a5fbe 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();
  }

a6d20f446f Use separate named MDNode to hold each function's local variable info.
