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.

octal encoded character after \c. This seemed to be prohibited at
r13836, but its ChangeLog mentions nothing about this prohibition.
So I assume this prohibition is not intended. [ruby-core:27229]

* parse.y (xstring, regexp, dsym, literal_concat, evstr2dstr):
literal at the top of dstr is no longer needed if it is empty,
since concatstrings and toregexp always create new strings.
