Update chown/permission_error test to work, even when uid/gid is 1000.

Previously, this test assumed that calling chown 1000:1000 file.txt was
invalid. That turns out to be valid if the current uid/gid is 1000/1000.

Update the test to take uid/gid as config consts and then add one to both to
get invalid uid/gid value.
Annotate the nights where NPB EP and IS performed better, used -E

I had misinterpretted the desire to use -E as a desire to use it nightly rather
than a desire to maintain default behavior but compare it to tweaked behavior.
Since there isn't a good way to compare them (our execenvs don't allow multiple
settings), decided to just leave the default for now.
Send darwin regression mail to normal lists (for gasnet.darwin)

Previously it was only sent to the all regressions list. The non-deterministic
errors have been cleaned up so it makes sense to send it to the normal lists.

Same idea as 7ad1f14e2a6f5febba3a03754c3487b5be7869f4, but I missed this file
Introduce transitional CForLoop::loopHeaderSet(init, test, incr)

Annotate the nights where NPB EP and IS performed better, used -E

I had misinterpretted the desire to use -E as a desire to use it nightly rather
than a desire to maintain default behavior but compare it to tweaked behavior.
Since there isn't a good way to compare them (our execenvs don't allow multiple
settings), we decided to just leave the default for now. Since that churn is
reflected in the nightly graphs, annotate it so we don't forget.

Note, the commit in question also affected FT, but for sizes we don't run nightly.
Move the blockTag assignment in to loopHeaderSet
