* compile.c (compile_array_): modify wrong optimization.

  A script "[print(1)]; print(2)" should output "12".
  However, the compiler had eliminted "[print(1)]" expression
  because it is void expression (unused array).
  Of course, side-effect should be remained.
  This issue is reported by Masaya Tarui.
* bootstraptest/test_literal.rb: add a test.
