Chung-Lin Tang 2766448c5c openmp: Fix libgomp.c++ testsuite errors for non-offload configs
Some testcases for libgomp.c++ only works for non-shared address space offloading,
because it exercises the zero-length array section behavior for offloaded
address space, testing for NULL/non-NULL cases.

libgomp/ChangeLog:

	* testsuite/libgomp.c++/target-lambda-1.C: Only run under
	"target offload_device_nonshared_as"
	* testsuite/libgomp.c++/target-this-3.C: Likewise.
	* testsuite/libgomp.c++/target-this-4.C: Likewise.
