Merge commit 'd6096a67422534918405abb46dafbbac4608cbc3'

* commit 'd6096a67422534918405abb46dafbbac4608cbc3':
  Remove all SH4 architecture optimizations

Conflicts:
	libavcodec/sh4/dsputil_sh4.c
	libavcodec/sh4/dsputil_sh4.h
	libavcodec/sh4/idct_sh4.c
	libavcodec/sh4/sh4.h

If someone wants to maintain these (or other) SH4 optimizations, please
contact me or ffmpeg-devel.
I am happy to revert this removial if theres someone considering to
maintain this code.
