* iseq.c (iseq_translate): at the end of constructing an iseq,

Browse source 
call RubyVM::InstructionSequence.translate(iseq) if this method
  is defined. If the return value is also an object of
  RubyVM::InstructionSequence, then use it instead of created one.

  For example, this method is useful to test iseq dumper/loader
  such as RubyVM::InstructionSequence#to_a and rb_iseq_load().

  Because this method is for such internal experimental usage,
  the interface is not matured. For example, this interface has
  no extensibility. Two or more translaters can not run
  simultaneously.

  So that we don't guarantee future compatibility of this method.
  Basically, do not use this method.
