    testsuite: Compile asan_test.C with -Wno-alloc-size-larger-than
    
    asan_test.cc tries to allocate 0xf0000000 bytes for 32bit targets in
    a disabled DISABLED_DemoOOM test.  Since the testcase is compiled with
    -Werror, the compilation fails with:
    
    error: argument 1 value '4026531840' exceeds maximum object size 2147483647
    
    Compile with -Wno-alloc-size-larger-than to avoid compilation failure.
    
            * g++.dg/asan/asan_test.C (dg-options): Add
            -Wno-alloc-size-larger-than.
