Updating REGRESSIONS from past 24 hours or so

New errors
----------
* LeakedMemory5 is now not finding its suppression (probably fixed with
  Lydia's baseline string leaks fix -- have alerted her)


Resolved errors
---------------
* Removed pervasive I/O sporadic failures from x?-wb.* category, as they
  seem to be cleared up (thanks Mike!!!)

* Removed lulesh failures from x?-wb.prgenv-cray as they seem to have
  self-resolved (due to the above?  Or something else?  Thanks masked man!)

* Removed baseline failures due to different amounts of string data leaked
  (thanks Lydia!)

* StringImpl/memLeaks/promotion also seems fixed (thanks Lydia!)


Misc
----
* moved StringImpl/memLeaks/coforall down to gasnet.fifo as that's the only
  place I ever see it fail

* noted compopts addition to parSafeMember test
