1. The RD scores obtained during the tx size selection were stored in the tx cache, and used to help make the tx decision for the following frames. This wasn't used anymore in VP9 encoder. Recovered the related decision making code from 1.5+ years ago, and borg tests didn't show any quality gain. This patch removed it to lower the complexity. 2. An optimization was done after the above refactoring. If the tx_mode is not TX_MODE_SELECT, we only need to test the chosen tx size instead of all posible tx sizes. This gave a 1.5% average speed gain at speed 2, and a 1% average speed gain at speed 3. Change-Id: Id8cd650e066a8cef33829d8c15388a8138adc78c
