Fix a bug of peephole optimization
``` 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]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63868 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
