Updates made in this patch:

1. Implemented @philip.pfaffe 's fixed-point iteration idea to decide the invariant loads, which also solves the instability issue of the previous approach.
2. Added Doxygen comment for the newly introduced parameter.
3. Renamed the temporary variables according to LLVM standards.
4. Used `foreach` for iterating over the invariant load set.
