Adjusted comm counts in .good for ChapelRangeBase merge.
Merge pull request #126 from vasslitvinov/adjust-good-files-for-improved-comm-counts

Adjusted comm counts in .good for ChapelRangeBase merge.

Get counts on remote locales improved by 2 for each of these two tests.

I confirmed that the improvement corresponds to ChapelRangeBase
merge (*), and did not look for a specific reason.
I am updating the two .good files with the improved counts.

(*) That means going from the merge of #95 to the merge of #90,
equivalently from commit 76d0ac6 to commit 20e2be7.
Merge pull request #93 from tzakian/lustre
