fd052ec753 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.

1b05ea8ffe ARM assembler for resampling. Should provide some gains, though not huge ones.

9636c1b61e Adapt ARM crossfeed assembler to work like the Coldfire one. Remove SWITCHPARAM cruft as it's no longer needed.

56f2ca74ad Assembler optimised crossfeed routine for ARM. Performance improvement is more than double. Should work fine, but watch your ears nevertheless.
