Try loading msdiaNNN.dll if CoCreateInstance(CLSID_DiaSource) fails

Browse Source 
Because tools/windows/symupload/symupload.cc uses `nullptr` (which
requires VS2010), the CLSID comparison is only performed for msdia100.dll
and later. When compiling with an older (or future) CLSID_DiaSource, we
retain the existing behaviour (i.e. fail if CoCreateInstance fails).
