5177413d20 alac: conditionally set sign_modifier to 1 
It is already unconditionally set to 0 prior to this, so we can modify it
only when needed.

7e6593e977 alac: eliminate 2 unneeded local variables in bastardized_rice_decompress() 
x_modified is just unnecessary, and final_val can be removed by simplifying
the unsigned-to-signed conversion.

28f9ab7029 vp3: move idct and loop filter pointers to new vp3dsp context 
This moves all VP3-specific function pointers from dsputil to a
new vp3dsp context.  There is no reason to ever use the VP3 IDCT
where an MPEG2 IDCT is expected or vice versa.

4cfb0d871d tscc2: do not add/subtract 128 bias during DCT 
It turns out that the reference decoder subtracts 128 from DC during block
decode but adds it back during reordering block with zigzag pattern.
Transforming block with incorrect DC caused heavy visual artifacts for
many quantisers.

951455c1c1 vp8: implement sliced threading 
Testing gives 25-30% gain on HD clips with two threads and
up to 50% gain with eight threads.

Sliced threading uses more memory than single or frame threading.

Frame threading and single threading keep the previous memory
layout.

f27386cdc7 x86: h264_intrapred: Don't add the 'd' suffix to the SPLATB_REG macro 
The SPLATB_REG macro already adds the 'd' suffix internally.

This fixes building on Win64, which has been broken since 878e66902.

This worked for unix, where r2 happened to be rdx in this case, which
with the first suffix rdxd was mapped to eax, and eaxd is defined back
to eax. On win64 however, r2 happened to be R8 in this case, and
R8d mapps to R8D just fine, but there's no mapping for R8Dd to anything.
