Enable SSSE3 inverse 2D-DCT with 10 non-zero coeffs This commit enables SSSE3 implementation of the inverse 2D-DCT with only first 10 coefficients non-zero. It reduces the runtime of SSE2 version from 745 cycles to 538 cycles, i.e., 27% speed-up. Change-Id: I18ba4128859b09c704a6ee361d69a86c09fe8dfe
