implementing 'exit' chunk splitting
basicly, this needs to:
* split with new label = dead code
* collect current chunk
ok.. this, together with factoring out the target-post code and dead
code elimination, which is now as good as free, seem to work fine.
small fix: instead of eliminating dead code, it's better not to
generate it in the first place: compiler will drop when code is not
associated to a label.
