This breaks < SM4 shaders, those don't have an explicit return
instruction at the end.

In general, each patch should pass the wine tests. Please run the d3d
tests and make sure that none are broken by your patchset.
Specifically, this patch breaks the d3d9 visual test pretty badly. It
looks like there are more failures introduced by other patches in the
series but I haven't tracked them down.

I think this should actually be "epilogue".
