We don't need these functions anymore. The only one which was actually
used is vp9_add_constant_residual_32x32. Addition of
vp9_short_idct32x32_1_add eliminates this single usage. SSE2 optimized
version of vp9_short_idct32x32_1_add will be added in the next patch set,
right now it is only C implementation. Now we have all idct functions
implemented in a consistent manner.

Making name consistent with vp9_short_idct8x8 and vp9_short_idct8x8_1.

about 6x faster than C version.

The 32x32 forward transform can potentially reach peak coefficient
value close to 32700, while the rounding factor can go upto 610.
This could cause overflow issue in the SSSE3 implementation of 32x32
quantization process.

This commit resolves this issue by replacing the addition operations
with saturated addition operations in 32x32 block quantization.

This commit fixed the potential overflow issue in the SSE2
implementation of 32x32 forward DCT. It resolved the corrupted
coded frames in the border of scenes.

The 32x32 quantization process can potentially have the intermediate
stacks over 16-bit range, thereby causing enc/dec mismatch. This commit
fixes this overflow issue in the SSSE3 implementation, as well as the
prototype, of 32x32 quantization.

This fixes issue 607 from webm@googlecode.

vp9_short_idct10_16x16_add is used to handle the block that only have valid data
at top left 4x4 block. All the other datas are 0. So we could cut many
unnecessary calculations in order to save instructions.

The inverse 32x32 transform detects all zero entries and skips the
computations accordingly per 8 rows in the first 1-D operation. The
function vp9_short_idct10_32x32_add performs differently and is not
used anywhere, hence removed.
