Alan Modra 47f6dab9a3 Rewrite SPU overlay handling code. Put overlay calls stubs in the
overlays where possible.  Use a faster call stub, or optionally at
	compile time, a more compact stub.  Double size of _ovly_buf_table
	so that low bit of _ovly_table.buf can be used as a "present" bit.
	Reserve an extra _ovly_table entry for index zero.
