freedreno/ir3: add last-baryf shaderdb stat
Sometimes sched changes that are a win in terms of instruction count and/or register pressure, are worse in real life, due to keeping varying storage locked for too long. Add a shader-db stat to give this more visibility. Signed-off-by: Rob Clark <[email protected]>
