Save/restore stack in try-expressions (and statements).

Parse TryCatchBlockNode's in generated bytecode, infer stack save/restore points.
Save stack to local variables before 'try'.
Restore stack after the beginning of try-block, catch-block, and default handler.
Integrate before/after inline markers rewriting (otherwise it'll break our stacks).
