[Alexandre Julliard]

Module: vkd3d
Branch: master
Commit: 78d95889bd49c6028f0c26aaec5589786381da4a

vkd3d-shader: Make *src and *dst mutable in vkd3d_shader_instruction.

They were originally made const because no optimization/normalization
pass existed. Now having to cast away const all the time is becoming
more and more burdening.
