Addressed comments.

- Used `union`s where the same memory is used for different purposes to make overlapping use of the memory more clear.
- Renamed variables to be more descriptive.
- Added a high level description of the state table based EH.
- Added comments in various locations.
- Fixed a problem where the frame pointer is needed to calculate the address.
- Fixed the address calculation of virtual base object for calling destructor or deletor to be based on the IBM object model used by the proprietary `xlC` compiler because these paths are only used for `xlC` generated code.
- Commoned up some code to reduce redundancy.
