When you change this to true, you may need to add more tests.

  and a pre-compilation/runtime loader sample.
  [Feature #11788]

* iseq.c: add new methods:
  * RubyVM::InstructionSequence#to_binary_format(extra_data = nil)
  * RubyVM::InstructionSequence.from_binary_format(binary)
  * RubyVM::InstructionSequence.from_binary_format_extra_data(binary)

* compile.c: implement body of this new feature.

* load.c (rb_load_internal0), iseq.c (rb_iseq_load_iseq):
  call RubyVM::InstructionSequence.load_iseq(fname) with
  loading script name if this method is defined.

  We can return any ISeq object as a result value.
  Otherwise loading will be continue as usual.

  This interface is not matured and is not extensible.
  So that we don't guarantee the future compatibility of this method.
  Basically, you should'nt use this method.

* iseq.h: move ISEQ_MAJOR/MINOR_VERSION (and some definitions)
  from iseq.c.

* encoding.c (rb_data_is_encoding), internal.h: added.

* vm_core.h: add several supports for lazy load.
  * add USE_LAZY_LOAD macro to specify enable or disable of
    this feature.
  * add several fields to rb_iseq_t.
  * introduce new macro rb_iseq_check().

* insns.def: some check for lazy loading feature.

* vm_insnhelper.c: ditto.

* proc.c: ditto.

* vm.c: ditto.

* test/lib/iseq_loader_checker.rb: enabled iff suitable
  environment variables are provided.

* test/runner.rb: enable lib/iseq_loader_checker.rb.

* sample/iseq_loader.rb: add sample compiler and loader.

    $ ruby sample/iseq_loader.rb [dir]

  will compile all ruby scripts in [dir].
  With default setting, this compile creates *.rb.yarb files
  in same directory of target .rb scripts.

    $ ruby -r sample/iseq_loader.rb [app]

  will run with enable to load compiled binary data.

  If you enable this checker (remove `#' in test/runner.rb),
  you can see comparison results between an original iseq disassembed
  result and dumped and loaded iseq disassembed result.

  There are several bugs around there, because of inexact stack depth
  calculation. Now, I leave these bugs because they are not critical
  and difficult to solve completely.

* test/runner.rb: require test/lib/iseq_loader_checker.rb but
  disabled at default (commented out).
