    libgomp.c++/static-aggr-constructor-destructor-{1,2}.C: Fix scan-tree-dump
    
    In principle, the optimized dump should be the same on the host, but as
    'nohost' is not handled, is is present. However when ENABLE_OFFLOADING is
    false, it is handled early enough to remove the function.
    
    libgomp/ChangeLog:
    
            * testsuite/libgomp.c++/static-aggr-constructor-destructor-1.C: 
Split
            scan-tree-dump into with and without target offload_target_any.
            * testsuite/libgomp.c++/static-aggr-constructor-destructor-2.C:
            Likewise.
