Support 'break' and 'continue' in expressions

- generate fake jump instructions so that we can always analyze stack depths
- fix stack before break and continue by dropping excessive elements (e.g., *a*.foo(*b*, c?:continue))
- Analyzer rewritten in Kotlin, with more flexible control of CFG traversal
