41a350a83d Change eob threshold for partial inverse 8x8 2D-DCT to 12
The scanning order has the first 12 coefficients of the 8x8 2D-DCT
sitting in the top left 4x4 block. Hence the partial inverse 8x8
2D-DCT allows to handle cases with eob below 12.

The overall runtime of the inverse 8x8 2D-DCT unit is reduced from
166 cycles (using SSE2) to 150 cycles (using SSSE3).

6e4a03e844 Removing "_1d" suffix from mips transform code.
Unifying transform function names across libvpx, 1d is a redundant suffix.
