SWCODEC, Coldfire, upsampling: Shave a couple more cycles out of the typical case and I think four bytes. Don't wanna look at this again for awhile. :)

SWCODEC-Coldfire: Small upsampling tweek improves speed and size a tiny bit and prevents unneeded reloading of the previous sample. I imagine it would help most with non-iram source buffers.

SWCODEC: DSP optimizations for conversion to internal format and resampling. Assembly resampling for Coldfire. Word has it ARM will get that soon.

new options is appreciated. Thanks to Dan Everton for the settings/GUI

Keep assembler versions of DSP routines in dsp_arch.S files. This also

solves the annoying register allocator problem when not using
-fomit-frame-pointer for the Coldfire assembler optimised crossfeed
routine.
