Portal Player: Add invalidate_icache and flush_icache. Flush the cache on the core for newborn threads. In doing so, move more ARM stuff to the target tree and organize it to make a clean job of it. If anything isn't appropriate for some particular device give a hollar or even just fix it by some added #ifdefing. I was informed that the PP targets are register compatible so I'm going off that advice. The Sansa likes it though.
