Speed feature to binary search dir intramodes This speed feature will skip searching the directional intra prediction modes D63, D117, D27, D153 if the best intra mode so far is not one of the diagonal, horizontal or vertical directions closest to the respective directions being tested. In other words, this implements a sort of binary search in the angular domain. Speedup: about 9-10% Results: -0.05% only on derfraw300. Change-Id: I413584c41f2a3e8dabfbdeb40718c8fc4b1d63a2
