new test case

This issue has been resolved in trunk r236678. I forgot to include a PR tag in
the ChangeLog entry. 

To verify the fix, I modified the original test case to make it executable in
the libgomp test suite. Furthermore, I changed parallel regions to parallel
loop regions so that the reduction yields sane results with multiple gangs.
I'll commit this test case to trunk with the proper PR tag in the ChangeLog
entry before I close this issue.
