[Mesa-dev] [PATCH 5/5] i965/vec4: print predicate control at brw_vec4 dump_instruction

[Alejandro Piñeiro]

---

I found this useful while I was using INTEL_DEBUG=optimizer after
changing how the ifs are emitted. And after all, that info is
also included by brw_disasm.c

I assumed that at the vec4_visitor we would not need to handle
pred_ctrl_align1, but Im not totally sure.
