Several changes in this revision:

1. The pass now extends PassInfoMixin<> instead of FunctionPass. A wrapper legacy pass that extends FunctionPass was also added.
2. The pass is now also used in the PassBuilder::buildFunctionSimplificationPipeline flow.
3. Style:
  - Using SmallVectorImpl instead of SmallVector when possible, in order to avoid explicitly stating its size.
  - Using SmallVectorImpl instead of SmallVector when possible, in order to avoid explicitly stating its size.
  - Other miscellaneous small fixes following code review comments.
