// Hackaround for Bug 1607574. Nvidia's shim driver nvd3d9wrap[x].dll
// detours LoadLibraryExW when it's loaded and the detour function causes
// AV when the code tries to access data pointing to an address within
// unloaded nvinit[x].dll.
// The crashing code is executed when a given parameter is "detoured.dll"
// and OS version is older than 6.2. We hit that crash at the following
// call to LoadLibraryEx even if we specify LOAD_LIBRARY_AS_DATAFILE.
// We work around it by skipping LoadLibraryEx, and add a library info with
// a dummy breakpad id instead.
