Clean up some more regressions from #420 sync-var-by-ref

Nightly testing under FIFO with futures turned out some regressions.
I cleaned up some, added .bad, retired two obvious .futures.
Mostly I added .readFE/.readFF().
The log file did not have any fallouts from the new error
for min/max on sync/single/atomics.

I did not clean up the missing-.readFE error in these tests:
  test/types/single/sungeun/writeRecordInOutProc.future
  test/types/sync/sungeun/writeRecordInOutProc.future
  test/types/sync/sungeun/writeRecordOutProc.chpl

because they raise the issue we did not tackle in #420
and which we should discuss first.
