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.
