Technically, this is correct, and I think it's the right long-term
solution. However, Iris has code that undoes the damage caused by
nir_lower_passthrough_edgeflags (see iris_fix_edge_flags in
iris_program.c), so it should be safe to do the lowering here.
I'm not marking this as closing mesa#4838 because I think we should move
the Iris code up to here, make a different version of the NIR pass, or
something different... to properly fix this problem. In the mean time,
this gets a bunch of tests to stop crashing. :)
