This PR adds an initial implementation for side exits.
It exits to the interpreter correctly when the current frame is pushed by the interpreter. When it's pushed by JIT, however, it panics inside
rewind_caller_frames(). It should materialize fields that JIT-to-JIT calls skip to write, which is to be done in a separate PR.
