Commit fca0f0e5 authored by Zdenek Kabelac's avatar Zdenek Kabelac

* removed MANGLE from macros for setting constants

* using MOVQ_WONE/MOVQ_BFE as two instruction instead of static memory value access
  as its always faster
* PAVGB_MMX macro is using now mm6 -> mm7 is unmodified
* replaced original pixels_xy2_mmx with new faster and equal implementation
* replaced usage of mm7 for other then ZERO contstant in _rnd & _avg file with mm6
