Adds vp8_sub_pixel_variance16x16_armv6 function to encoder. Integrates ARMv6 optimized bilinear interpolations from vp8/common/arm/armv6 and adds new assembly file for variance16x16 calculation. - vp8_filter_block2d_bil_first_pass_armv6 (integrated) - vp8_filter_block2d_bil_second_pass_armv6 (integrated) - vp8_variance16x16_armv6 (new) - bilinearfilter_arm.h (new) Change-Id: I18a8331ce7d031ceedd6cd415ecacb0c8f3392db
