Original patch written by David Anderson (original r from Fyren).
- Updated to function with the current JIT compiler.
- Took in clean-ups from later-dated patches.
I accidentally changed the debug table packing in a commit a while ago. This explains the nonsense debug output and crashes people have been getting on the 1.1 branch. Fortunately this is (mostly) detectable via the "debug.natives" table and the JIT will unpack symbols based on that information.
1) JIT compilation/optimization now occurs per-function, and only when functions are first used. We're now officially a whole-method JIT rather than an AOT compiler (albiet, still a simple JIT). This has two implications: Functions are now much better abstracted internally, and loading a plugin is now much less expensive. If a function contains calls to other functions, THOSE functions are only compiled when they're invoked as well.
2) I've removed debug mode. We always show full backtraces now, as there was a very cheap way to implement this which really cleaned up everything. This is great for a number of reasons -- there's less code, the JIT is better designed, we don't need to relocate debug tables, and best of all we no longer have to tell users to enable debug mode at their own expense.

NOTE: the JIT is now embeddable out-of-box and usable by other projects which is pretty cool. I will commit a shell app demonstrating this soon
