* compile.c (compile_array, compile_array_):

  Divide big array (or hash) literals into several blocks and
  concatetene them.  There was a problem that a big array (hash)
  literal causes SystemStackError exception (stack overflow)
  because VM push all contents of the literal onto VM stack to
  make an array (or hash).  To solve this issue, we make several
  arrays (hashes) and concatenate them to make a big array (hash)
  object.
  ??
* compile.c (iseq_compile_each, setup_args): use modified
  compile_array.
* vm.c (m_core_hash_from_ary, m_core_hash_merge_ary,
  m_core_hash_merge_ptr): added for above change.
* id.c (Init_id), parse.y: add core method ids.
* bootstraptest/test_literal.rb: add simple tests.
* bootstraptest/test_eval.rb: remove rescue clause to catch
  SystemStackError exception.
* test/ruby/test_literal.rb: add tests to check no stack overflow.
