Ryan Macnak 6664e3c02a [vm, dbc] Implement lazily-linked natives for DBC and enable AppJIT. 
Because DBC still uses code patching to implement breakpoints, running a program from DBC AppJIT may trigger a crash attempting to set a breakpoint.

Ryan Macnak fda4ab3dbf [vm] Move the info_array for ObjectPool inline. 
The info_array is needed to visit an ObjectPool's pointers, requiring the compactor to move the info_array's body before forwarding the ObjectPool's pointers. Moving the info_array inline remove this constraint on the compactor.

Also saves 3 words per ObjectPool modulo allocation size rounding.

Vyacheslav Egorov 8a179fb953 [VM, Compiler] Move compiler to a separate folder. 
New folder structure (nested under vm/):

- compiler/
-   jit/         - JIT specific code
-   aot/         - AOT specific code
-   backend/     - all middle-end and back-end code (IL, flow graph)
-   assembler/   - assemblers and disassemblers
-   frontend/    - front ends (AST -> IL, Kernel -> IL)

compiler/README.md would be the documentation root for the compiler
pipeline
