This is a port of the inline assembly of the mmx version to use the
pavg(us|)b instruction.

Currently, only the mmx version is bitexact, the others (mmxext and
3dnow) are not, in spite of their naming.

Therefore, make their name more obvious. Also restore a comment that
was removed in 71155d7b.

recode_subtitle() is called implicitly by avformat_find_stream_info().
As such, clients which disable ICONV always crash if a file contains
subtitles; even if they don't care about them.

Fixes Ticket3653
Signed-off-by: NMichael Niedermayer <michaelni@gmx.at>

The original code left-shifts negative values, which is undefined
in the C99 specification (the one used during normal FFmpeg compilation).
This change multiplies by (1 << shift), which is functionally equivalent,
but has defined behavior.
With this change, fate-idct8x8 compiled with --fsanitize=undefined works.
