JIT hackery. Not quite working.
Source map in DebugInfo. IVM needs to port its stuff over eventually.
Fixing source offsets.
Removing block continuation branches.
Reducing value count. IVM could take advantage of this.
(air quotes) "register allocation" without spills.
Heuristically detecting ret - probably breaks some things.
Removing SET_RETURN_ADDRESS - hopefully it'll never be needed again.
Fancy templated helpers.
Making debug disassembly look a bit better.
Fixing stack size.
Logging comments like IVM.
Fiddling with stack. Still wrong.
