nir/dead_cf: Stop relying on liveness analysis
The liveness analysis pass is fairly expensive because it has to build
large bit-sets and run a fix-point algorithm on them. Instead of
requiring liveness for detecting if values escape a CF node, just take
advantage of the structured nature of NIR and use block indices instead.
This only requires the block index metadata which is the fastest we have
metadata to generate.
