swresample: change COMMON_CORE_INT16 asm from SSSE3 to SSE2
pshuf+paddd is slightly faster than phaddd.
The real gain is in pre-ssse3 processors like AMD K8 and K10, which get
a big boost in performance compared to the mmxext version

swr/resample: move templating parameters to template itself.
It has various benefits such as allowing some refactoring, clarifying
the code in the inclusion part, and making the template understandable
in standalone.
This commit is based on the templating method used by Justin Ruggles for
libavresample.
