Disable -ftrivial-auto-var-init= for hot code
Improves encode_time by 10% on FullStackTest.VP9KSVC_3SL_High and other
tests when -ftrivial-auto-var-init= is used.
vp9_pick_inter_mode can be called recursevely so multiple pred_buf is
neede. So alternative to attribute should be list of bufferes in
ThreadData or TileData.
