Cell: first triangle.

This is a feeble first step, but it works.
The cell_clear_surface() function has been hijacked to set up a "draw triangle"
command and send it to all the SPUs.
The Gallium softpipe triangle code was copied to the SPU module and modified.
Only the progs/trivial/clear.c program runs.
