* iseq.c: add RubyVM::InstructionSequence (ISeq) inspection methods.

Browse source 
* ISeq#path returns path of this ISeq written.
* ISeq#absolute_path returns absolute path.
* ISeq#label returns label (method name and so on).
* ISeq#base_label returns base label (see Thread::Backtrace::Location).
* ISeq#first_lineno returns first line number of this ISeq.
* ISeq.of(obj) returns ISeq object which obj (Proc or Method)
  is contains.
* test/ruby/test_iseq.rb: add tests.
