Implemented DST 8x8 with SSE2 intrinsics. Implemented fdst8_sse2() function against C version: fdst8(). Added seven DST related hybrid transform types in vp10_fht8x8_sse2(). Replaced vp10_fht8x8_c() with vp10_fht8x8_sse2() in fwd_txfm_8x8(). Speedup: 18.1%, 11.5%, 22.0% based on speed test from city_cif.y4m, garden_sif.y4m, mobile_cif.y4m.
