For some historical reason, coefficients of interpolation filters in filter.c is defined in int16_t but use 8 bits only. On the other hand, SIMD like to use int8_t to represent those coefficients for economical reason. The conversion from int16_t to int8_t will introduce "possible loss of data" warning. We use cast to work around this problem. Change-Id: I42ef0a2a815a8f93c579f7984c9b957c1aed6d6c
