Hi!
As mentioned in the PR and now that the middle-end bug is fixed, this fixes
thinkos in the testcase; the result variable has to be omp declare target,
otherwise the declared target functions called from the target regions can't
access it.
The testcase still fails to assemble due to exceptions, but that is
something to be fixed in the nvptx backend (sure, we could add
-fno-exceptions temporarily though for nvptx offloading only).

* testsuite/libgomp.c++/for-15.C (results): Include it in
omp declare target region.
(main): Use map (always, tofrom: results) instead of
map (tofrom: results).
