Updating REGRESSIONS based on this afternoon's negative results

New regressions
---------------

* two failures in studies/lsms due to jgit/symbolic link issue on
  linux32 and xe-wb* (vass/thomas).  Hoisted this into a general
  category now that we're seeing it on linux32 as well.

* new linux32 failures due to running all of examples for the first time:
  - 6 io/ferguson/ctests fail due to a bad #include of the task header
  - 8 GMP tests fail due to Chapel vs. C int size differences
  - 12 tests fail because memmax/memthreshold are defined as C rather than
    Chapel types, so don't have well-defined sizes as they should
  - 1 failure due to different amounts of memory being leaked, presumably
    due to different pointer sizes
  - 1 failure due to lack of prefetch support (I believe)
  - 1 failure due to some sort of 64-bit assertion failures in
    chpl-cache-support-test
  - 4 timeouts in familiar tests: cobeginRace, parSafeMember,
    manyThreads-inorder, test_10k_begins

* new cobegin-stacksize failures in GASNet due to lack of launcher support
  for -E

Improvements
------------
* removed chpl_glob general failure as it's now draining from xe-wb*

Misc
----
* updated some sporadic failure dates
