I know that in theory, TemporaryFile is very simple and unlikely to fail.  In practice, though, Windows can be very finicky about deleting files, so it might be nice to add a test for TemporaryFile.  I'm surprised LLVM doesn't already have such a class that's already well-tested.

I don't think the `explicit` does anything here, since the constructor requires two parameters.

----------------
I'm concerned the assertion could fail sporadically on Windows, since there's a delay between asking for the file to be deleted and the actual deletion of the file.
