Only enable it for CPUs that support it.
This restores the behavior prior to 7a650caf.

The specification uses lower case most of the time.

Print the UL in code format and in the short format used by the
specification.

Some files set the PreviousPartition field to point to its own offset.

If we are parsing forward the Previous partition is immediately known
and its value could be used, otherwise we can safely point to the
header.

Ported from arm NEON and added vector_dmul_scalar.

Functions between 1.5 and 5 times faster than the C implementations
using Apple's clang-503.0.19 on A7.

Avoids a warning of the unused function 'autocorrelate'.

The code using it was removed in d66e305b.

Drop the mpegvideo dependency for svq3 in configure.

Unused buffers scratchpad and temp have been dropped too.

This is done to disentangle ER from mpegvideo. In order to use a
classic Picture, callers can use ff_mpeg_set_erpic() or use a custom function
to set the fields. Please note that buffers need to be allocated before
calling ff_er_frame_end().
