A vertex-path program with LDS, GDS or memory writes refused any s_barrier. NGG passthrough
programs start with the s_barrier that orders GS_ALLOC_REQ, before any memory access, and some
write buffers later. A barrier that runs before every load, store, atomic, image or LDS access of
the program has nothing to order, so it emits no instruction, like the barrier of a program
without memory access. Barriers after a memory access still throw.
