The only benefit of FunctionPass is that it filters out function declarations. This isn't enough to justify carrying it around, as we can simplify filter out declarations when necessary within the pass. We can also explore with better scheduling primitives to filter out declarations at the pipeline level in the future. The definition of FunctionPass is left intact for now to allow time for downstream users to migrate. Differential Revision: https://reviews.llvm.org/D117182
