Hi,

this patch avoids run-time failures in libgomp testsuite that
curtrently happen when HSA offloading is actually used.  All of them
currently require the offload_device effective target which the patch
changes to offload_device_nonshared_as one.

For some tests, such as libgomp.c/examples-4/device-1.c this is really
the correct thing to do because the test explicitely checks that
changes that happen in a target construct and are not mapped back are
not observable on the host.

However, the majority of the tests has a different problem.  The test
for some reason is not compiled into HSAIL (usually because it would
require the dynamic parallelism path which is disabled or because it
calls abort from within target which HSA so far cannot handle) and so
the host fallback is called, even though the test actually is not
supposed to be called on it.  The tests then call
omp_is_initial_device to verify they are not running on the host and
decide to fail.

Changing the effective target only to devices with non-shared memory
probably isn't the really correct fix.  We basically want to disable
the host fallback for them regardeless of address spaces but I cannot
think of a simple and generic way of doing that.  However, all
testcases for non-shared memory devices were written with disallowed
fallback in mind and so this soulution also gives the desired result.

Tested both with and without HSA (enabled or present).  OK for trunk?

Thanks,

Martin
