ARM DSP: Add assembly custom sound channel processing. 13% to 14% faster than currently-used default C code on ARMv4.

Add arm assembler for dsp_apply_gain(). Speeds up this routine by 30-40% on PP502x.

FS#8894 - Add time stretching feature to all SWCODEC targets - the current algorithm is best for spoken word.

Commit FS#8750. Add ARM assembler for the dsp-functions channels_process_sound_chan_mono(), channels_process_sound_chan_karaoke(), sample_output_mono() and sample_output_stereo(). By measurement the speed up is ~75% for the first three functions and ~40% for sample_output_stereo(). Additionally avoid calling yield() to often in dsp.c -- it is now limited to once per tick.

Code cleaning - remove some unnecessary defined(SIMULATOR) checks

SWCODEC & Coldfire: Do some more DSP straigntening out. Do as much Coldfire optimizing as seems reasonably possible by jumping through some hoops to avoid stalls. Further boost reduction will just be fractional points if taken to extremes-- not worth it. Wrap up the ASM for awhile.

ARM assembler for resampling. Should provide some gains, though not huge ones.

Adapt ARM crossfeed assembler to work like the Coldfire one. Remove SWITCHPARAM cruft as it's no longer needed.
