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).
