It's a little undesirable to introduce multiple operations that are
largely the same, although I don't necessarily see a good way to avoid
it either right now.

I should have noticed this when
WINED3D_CS_OP_SET_UNORDERED_ACCESS_VIEW was introduced, but these are
between wined3d_cs_exec_set_shader_resource_view() and
wined3d_cs_emit_set_shader_resource_view(), please don't do that. More
generally, all the other handlers have execution above emission, I
think it's best to stick with that.
