> We generally apply dead code elimination implicitly in HOP DAG construction
> and according to the data flow analysis of used variables. However, with IPA
> and rewrites additional branches and function calls might get removed which
> sometimes creates additional opportunities for dead code elimination.
> Therefore, this task aims to add an IPA pass for dead code removal.
