[PATCH] D102736: Fix tmp files being left on Windows builds.

================
Comment at: clang/lib/Frontend/CompilerInstance.cpp:872
   // using stdin.
+  void *FileHandle = nullptr;
+#ifdef _WIN32
----------------
I'm saving the windows HANDLE here instead of using `fd` because for some reason calling `_get_osfhandle(fd)` in `UnmarkFileForDeletion` fails. 

It also doesn't work if I don't duplicate the handle, but I don't entirely understand why. (I think when we try to rename the file, it fails with file not found, so maybe it gets deleted?)
