Added per pixel inter rd hit count stats Added some code to output normalized rd hit count stats. In effect this approximates to the average number of rd operations/tests per pixel for the sequence. The results are not quite accurate and I have not bothered to account for partial SB64s at frame edges and for key frames However they do give some idea of the number of modes / prediction methods being tested for each pixel across the different partition sizes. This indicates how much scope their is for further gains either by reducing the number of partitions examined or the modes per partition through heuristics. Patch 3 moved place where count incremented so partial rd tests that are aborted with INT_MAX return are also counted. Example numbers for first 50 frames of Akiyo. Speed 0 ~84.4 rd operations / pixel Speed 1 ~28.8 Speed 2 ~11.9 Change-Id: Ib956e787e12f7fa8b12d3a1a2f6cda19a65a6cb8
