These fix failures of --enable-xmm-clobber-test
It would be better to change the code to use fewer registers, but until

For test images manually generated to contain only up prediction,
timing results:
8380x3032 255x185
before: 138635 1992
after: 139232 1996
Actually jumping to the proper version depending on the alignment:
8380x3032: 138767
A 0.5% speed improvement for gigantic images is not worth the code
duplication.
Fixes ticket #4148

~15% faster.
Also add an mmxext version that takes advantage of the new code, and
build it alongside with the mmx version only on x86_32.
