idct_put for compilers/architectures that can not align stack variables that much.
This is also consistent with similar code in eatgq.c

Might avoid crashes in unlikely cases, but mostly avoids ugly artefacts
for partial frames.

for idct_put on architectures/compilers that have problems aligning on the stack.

Fixes issue1102.

Originally committed as revision 18920 to svn://svn.ffmpeg.org/ffmpeg/trunk

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.

Just aligning it on the stack would have been possible but less reliable
and without any real benefit.
