fix peephole optimization.
* compile.c (iseq_peephole_optimize): do not need to put `pop` instruction. * test/ruby/test_optimization.rb (test_peephole_optimization_without_trace): This code "def foo; 1.times{|(a), &b| nil && a}; end" fails to compile by stack underflow because of above bug (fixed by this patch). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60724 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
