When letting the overlapping waves enter their ordered sections, there must
be no memory accesses to resources which need primitive-ordered access that
are still pending, or there would be a race between the current wave and
the overlapping waves.

If the wave has set the Primitive Ordered Pixel Shading packer ID hardware
register, it must send MSG_ORDERED_PS_DONE once before the program ends.
It's also safe to send the message if the packer ID register hasn't been
set yet, therefore the message may be sent conservatively. For simplicity,
to ensure that it's sent on all execution paths after setting the packer ID
register, always sending it from a top-level block. This is required for
GFX9-10.3 POPS.
