When adding a pass to the pipeline, there would be differences between in the generated code when the pass performed no operations, and when the pass was not present.

This pass adds dependencies for

- TargetTransformInfoWrapperPass
- TargetPassConfig
- LoopInfoWrapperPass
- TargetLibraryInfoWrapperPass

which are used but did not were not recorded using the `INITIALIZE_PASS_DEPENDENCY` macro to fix this inconsistency.
