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.

Cast some more to keep both 32 bit and 64 bit simulator platforms happy.

Oops. That ICONST_ATTR shouldn't be on the gauss table...yet. I leave experiments in a commit by accident way too much. :P What's the deal with getting SVN to update Id or add it? Nothing seems to work.

SPC codec on Coldfire: Urgh. There was a whole gain stage I overlooked. :P Kill another several boost points.

SPC codec on Coldfire: Move movclrs into the light and out of the long dark shadow cast my emac latency as much as possible. Put in a faster interpolation routine (emac saves the day...again). Add comments about what's going on.

SPC Codec: Fix an overflow issue in echo with left shifting by 9 that showed on some files by using mac.l instead which is ok since the little beastie seems to prefer multiplying things. Mark asm blocks volatile so gcc doesn't get any ideas that the code can be removed as happened to me once already.

SPC codec: enable echo on ColdFire CPU. Do a couple general small optimizations. Preswap some data when running DSP for big endian.
