Yaowu Xu 66d94ac13c Improve 32x32 forward dct 
The commit improves the 32x32 forward dct implementation:
1. change to use same constants and rounding as other forward dcts
2. select rounding to specifically minimize the roundtrip error, which
improved average 19/block to .77/block using 100000 random input.

Test showed a small but consistent gain on all test sets, about .15%
