bf14d468c1 Rewrite vpx_highbd_idct8x8_{12,64}_add_sse2 
This replaces commit aa1c4cd, which has a bug and was reverted in
commit 3c73e58.

The bug is caused by rounding -step1[5] in highbd_idct8x8_12_half1d().

d35b627340 Revert "Rewrite vpx_highbd_idct8x8_{12,64}_add_sse2" 
This reverts commit aa1c4cd140.

This fails the following tests with extreme input coefficients:
SSE2/InvTrans8x8DCT.CompareReference/0
SSE2/InvTrans8x8DCT.CompareReference/2

previously the optimized path was skipped in this range
