[XviD-devel] recent mmx patch (xvid_bench results)

[jmtest at voila.fr]

So i did remove the cmov instructions from the mmx code, but I don't have an old pentium to complete the tests.
The new code is ok with the crc bench and also with the exhaustive test.
I hope it's right this time...

Here is the speed result on a Pentium Mobile 1.5GHz
