It is enough to specify (e.g.) idct16, it is obviously different from
idct16x16.

We don't use different filter kernels for x and y, it is always one kernel
for both directions.

SSE for a 64x64 block with 3 planes can go as high as 3*2^28. So left
shift by 4 may overflow 32 bit int.

The sum of squared mv components can go beyond int range for large
 input resolution. This commit changed the type to int64 to avoid
overflow.
