Removing vp9_idct4_1d_sse2 function.
We have two SSE2-optimized functions for idct4_1d:
vp9_idct4_1d_sse2 <-- removing this one
idct4_1d_sse2
vp9_idct4_1d_sse2 was used only by the following functions which already
have SSE2 optimized variants:
vp9_idct4x4_16_add_c -> vp9_idct4x4_16_add_see2
idct8_1d -> vp9_idct8x8_{16, 10, 1}_see2
vp9_short_iht4x4_add_c -> vp9_short_iht4x4_add_see2
