Mid-week update to REGRESSIONS

There's been a lot of cleanup the past few days, so updating
REGRESSIONS to reflect it:

* Removed --no-local and gasnet-fast failures due to r21733, fixed
  by Michael and Tom's commits, respectively

* Removed unclassified parboil failures which were the same issue
  in a different guise

* Removed printchplenv failure, fixed by Greg

* Updated description of hello-numThreads-1 failure

* Reordered, cleaned, primped some other stuff

Updating .future to clarify the  problem

Sung requested this (I'm guessing) to make her life simpler when
generating/updating the STATUS.devel file.
