Removing the TRIAGE file

A good idea, ultimately, it was unmaintainable.  Now using the
REGRESSIONS file for this purpose.
Updating REGRESSIONS based on today's returns
Merge pull request #845 from bradcray/triage-sep-blc

Final commit in "tyrannical reign of triage"

I'm giving up my hold on triage for SC14 and Thanksgiving.
Take care of things for me, team!

New regressions
---------------
* test/link/sungeun broken everywhere due to skipif mods (hilde)

* manyThreads-inorder doesn't print full output	on linux32 when	it doesn't
  timeout

* recordWithRefCopyFns fails under baseline for	not-well-understood reasons
  (hilde)

Improvements
------------
* Colorado State OpenMP tests resolved	for OpenMP-less	darwin (thanks Ben!)

* Colorado State C tests resolved	for gasnet* by removing -nl (thanks Kyle!)

* externRecordLostFields resolved for prgenv-intel (thanks Lydia!)


Misc
----
* removed TRIAGE file because it became	out of control and I'm tracking
  in REGRESSIONS now

* added new gnu.darwin category to test gcc on darwin -- only errors are
  test/link/sungeun (b/c broken	everywhere) and	cfd-mini-c (darwin-specific)
  NB to Thomas: changed to inherit from darwin for the second reason but
  Ben's improvement above suggests that this wouldn't have been right...
  suggests perhaps having a darwin* category that both 'darwin' and
  'gnu.darwin' inherit from as we discussed.

* did a	final deep review of all mails that came in today.  I think only
  some of the xe configurations are missing.

* removed playground categories	since we're not	running	them anymore

* unified formatting of	recordWithRefCopyFns issue

* pidigits on llvm has been getting suppressed;	Thomas unsuppressed it to
  be more uniform with other cases so it showed	up as a	"new" failure.

* noted gbt/diten's ownership of memleaks/coforall

* re-sorted cygwin to match mail order

* removed jacobi from sporadic dist-block failures on assumption that
  Elliot's new timeout changes helped

* removed ugni/muxed section due to it not being recent	combined with
  the fact that	we're currently	only testing examples.
