------- Additional Comments from Filip Pizlo <fpizlo at apple.com>
- hopefully fixed build issues, but not sure, because I don't see them on my
box.

- added loads of tests.

- found one additional, related, bug that the testing revealed: inlining code
was not correctly setting aside all 6 call frame slots because of an off-by-one
bug.
