incidentally -- these type checks are probably cheaper than
isSupportedOptionalType, so I wonder if it would make sense to put them first
in the function (though you'd need to rule out isGLValue). That would also
allow you to factor out the check of `DirectCallee == nullptr` from the two
other branches.
