Giovanni Mascellani d5fd309ef8 vkd3d: Add a macro to mark unreachable code.
This should silence warnings about some branches non returning any value
without requiring additional "return 0" statement or similar.

Also, in theory this might enable to compiler to optimize the program
a little bit more, though that's unlikely to have any measurable effect.
