```
if L1
L0:
jump L2
L1:
...
L2:
```
was wrongly optimized to:
```
unless L2
L0:
L1:
...
L2:
```
To make it conservative, this optimization is now disabled when there is
any label between `if` and `jump` instructions.
Fixes [Bug #14897].

fixes: Bug #2729
a patch from Kazuki Tsujimoto <kazuki@callcc.net>
This problem is caused by changing dfp (dynamic env pointer)
from saved dfp. Saved dfp is pointed env in VM stack. However,
the dfp can be moved because VM copies env from VM stack to
the heap. At this copying, dfp was also changed. To solve this
problem, I'll try to change throw mechanism (not save target dfp,
but save target cfp).
* bootstraptest/test_flow.rb: add a test for above.
