because it contains motion code.

As a side-effect this also gives it the correct value on e.g. PPC970FX-based
PPC64 systems, thus fixing "make test" (mp2/mp3 decoding).

into the context to avoid issues when stack variables can not be aligned

This is also consistent with similar code in eatgq.c

Might avoid crashes in unlikely cases, but mostly avoids ugly artefacts

This ensures that the MMX loop filter is always bitexact with the C version.

changeing calls to sub_left_prediction such that
the source frame data pointers are no longer offset to skip the initial
elements. This keeps them properly aligned for the subsequent call to diff_bytes.
Changes encoding offset to compensate.

Change all calls to pass zero for this new argument for equivalent behavior.
This is a restructure to support a forthcoming bug fix.

MLP DSP functions x86-optimized.
12.59% overall speedup in x86_32
9.98% overall speedup in x86_64
compared to gcc 4.3.3
It breaks on x86_64 with PIC because the MANGLE macro appends (%%rip), which
is not wanted for labels.

it is aligned as necessary for DSPContext's idct_put.
Just aligning it on the stack would have been possible but less reliable
and without any real benefit.

Now the sign of audio samples in ffvorbis output is the same as in original
uncompressed audio file and this also allows the use of tiny_psnr to compare
ffvorbis with libvorbis/tremor.
