CAR simplifications, typos, readability improvements (trivial).
- Use some more #defines instead of hard-coding values.
- Merge multiple movl/orl or movl/andl lines into one where possible.
- Add some TODOs in places which seem to have either an incorrect
code or incorrect comment.
- Fix typos: s/for/from/, s/BSC/BSP/, s/size/carsize/.
