Memory access fault
I wished I had a GPU that could be - at runtime - toggled
between not-shared memory, shared memory, and integrated GPU mode …
[OK, passing 'uvm_disable_hmm=1' to 'nvidia-uvm' works but means
rebooting …]

Fix this by 'map'ping 'x' for the OpenMP 'target' construct. Not technically
necessary for 'libgomp.c/target-device-type-2.c' (as that one's exercising the
'host' error case), but still apply the same change also to that one.
OK.
libgomp/
* testsuite/libgomp.c/target-device-type-1.c (f): Map 'x'.
* testsuite/libgomp.c/target-device-type-2.c (f): Likewise.
Thanks and sorry for the test fail!
