SPC Codec: Ensure no crash occurs on load failure which could cause emulation to be run without a program loaded on dual core (DSP wasn't initialized yet). The load failures come from core buffering not having the atomic audio file fully loaded before the codec requests the buffer (it gets as many bytes as can be provided) which IMHO isn't very atomic :). Changes in thread execution order after dumping spinlocks for general use simply revealed the buffering race condition. No fix for that will be hacked into the codec itself but should be fixed in the core. Add my copyright to files I had a significant part in developing per request of Adam Gashlin.

SPC/Coldfire: Just use msac.w instead of neg.l/mac.w. It seems fine. Must've been cache aliasing. :-)

Make the SPC codec run like it used to on Coldfire before -Os crushed it. Build as a lib using the old -O option. Should not impact ARM targets.
