SPC Codec: Refactor for CPU and clean up some things.

Browse source 
CPU optimization gets its own files in which to fill-in optimizable
routines.

Some pointless #if 0's for profiling need removal. Those macros are
empty if not profiling.

Force some functions that are undesirable to be force-inlined by the
compiler to be not inlined.
