Avoid redundant calculations in tpl

The following redundant computations in tpl module are avoided :
- Inverse transform when using source frame as reference.
- Rate and distortion calculation with source frame as
  reference when the best prediction mode is an intra mode.
- Start MV SAD computation when the number of start MVs
  used for motion search is 1.
