There are two issues here:
1. If there are any phi nodes, we'll make complete hash of them. This
isn't likely actually a problem because spirv_to_nir doesn't
generate any actual phi nodes today. However, if we start doing any
other passes before this, we may have a problem.
2. Even without phi nodes, we may still break SSA form. This can
happen if we ever have to stick a block inside a conditional to
satisfy weird CFG constraints. Doing so can cause it to no longer
look like it dominates some of its uses even though, at runtime,
it's guaranteed to be run first.
