nit: I read http://msdn.microsoft.com/en-us/library/aa652267(v=vs.71).aspx to
review this; maybe there should be a test for '0' too. Not very important.

     {
       'target_name': 'test_opt_wpo',
       'type': 'executable',
       'msvs_settings': {
         'VCCLCompilerTool': {
           'WholeProgramOptimization': 'true'
         }
       },
       'sources': ['hello.cc'],
     },
   ]
 }
