- vrend_decode_set_vertex_buffers
- vrend_decode_set_shader_buffers
- vrend_decode_set_atomic_buffers
- vrend_decode_set_shader_images
And change variable type to uint as the protocol should never send negative number.

Some varying outputs can be directly used for tranform feedback, so don't
emit an additional varying in these cases. This should save a move
instruction and also reduces the possibility of hitting the output varying
limit.
