 641         Rewrite SPU overlay handling code.  Put overlay calls stubs in the
 642         overlays where possible.  Use a faster call stub, or optionally at
 643         compile time, a more compact stub.  Double size of _ovly_buf_table
 644         so that low bit of _ovly_table.buf can be used as a "present" bit.
