ae904fd028 Fix issue #301: 
summary of changes:
- Use MANGLE when loading some constants into MMX registers.
- Convert those constants to non-static and thus add ff_ prefix.
- Remove last parameter of MSPEL_FILTER13_CORE (was constant).
- Use of "+r" instead of stricter but unnecessary "+g".
- Use of REG_c and direct loading of some of the above.

61240ae556 fix chroma mc2 bug, this is based on a patch by (Oleg Metelitsa oleg hitron co kr) 
and does slow the mc2 chroma put down, avg interrestingly seems unaffected speedwise on duron
this of course should be rather done in a way which doesnt slow it down but its better a few %
slower but correct then incorrect
