Doing some REGRESSIONS cleanup in anticipation of the release

Checked some of the recent/key Cron regressions output to make sure
that all of the unresolved regressions being reported match what we
have in the REGRESSIONS file.  The diffs were:

* added missing entries for printchplenv and hello-numThreads-1
  under gasnet-everything

* added missing entries for 3 parboil entries in the --no-local
  directory (which also fail under gasnet-fast)

* removed 13 gasnet-everything comm-count failures that now seem
  to be passing (due to RootLocale replication, presumably?); also
  added one that was missing (stream-ep_commDiags)

* --no-local seemed to get a bunch of the same regressions as
  gasnet-fast did (but gasnet-everything did not?  Huh?).  Refactored
  those cases into the --no-local section.

Also did some reformatting and re-sorting of things to match the
order listed in the cron output.
