1. Disable periodic statistics printing when no statistics were reported in the recent report interval
...
2. Fix regression in issue 88 (core dump in JIT after truncate table), and added missing index id copy in CloneJitContext()
3. Added support for FULL-SCAN SELECT in JIT execution
4. Added more JIT tests
5. Clarified JIT statistiscs (separated invocation count from execution count)
6. Added special JIT statistics for testing (outside of statistics infra)
7. Fixed JIT plan explanation
8. Added support for boolean operators in JIT expressions (in WHERE clause and UPDATE SET clause)
9. Fixed JIT range scan bug: when filter execution fails execution branches to the wrong place (effect is missing check of end-of-scan flag that can lead to crash)
10. Fixed JIT JOIN bug: resetting wrong scan-ended flag (effect is missing records in result set)
11. Fix bug in JIT plan: Allow complex filter expressions in JIT plan (effect was simple queries were disqualified for JIT execution)

修复了关于rownum的4个bug。
...
1.最大值只有255，正常应该是无限大。
2.group by跟where rownum < n同时存在时，禁止将rownum优化成limit
3.groupy by后面没有rownum，而having后面有rownum时，会正常运行，正常应该报错。
4.union前后的子句如果有where rownum < n，并且还有含有order by的子查询时，禁止将order by优化删除掉。
