    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.
