nir/opt_if: Remove unneeded phis if we make progress
Now that SSA values can be derefs and they have special rules, we have
to be a bit more careful about our LCSSA phis. In particular, we need
to clean up in case LCSSA ended up creating a phi node for a deref.
This fixes validation issues with some Vulkan CTS tests with the new
deref instructions.
