Add speed feature to skip repeat interp search
Add speed feature to skip repeat interpolation
filter search (turn on for speed>=1)
1. Save the search result and current mv and ref_frame
at the end of each search for one block
2. At the begining of each search, check the saved
results, if there is matched result which has same
mv and ref_frame, the result can be reused.
3. Clear saved result at the begining of
av1_rd_pick_inter_mode_sb, search result only reused
in the same block.
4. For encoder, about 2.5% faster shows by encoding
15 frame of BasketballDrill_832x480_50.y4m, with no
coding loss. ( 486668 ms -> 474152 ms)
