ruby--ruby/test/ruby/test_backtrace.rb
ko1 f6f769d26d * vm_backtrace.c: change names.
(1) Class name: RubyVM::FrameInfo -> RubyVM::Backtrace::Location.
  (2) Method name: RubyVM::FrameInfo.caller ->
  Kernel.caller_locations.
  (3) Instance methods of
  RubyVM::FrameInfo (RubyVM::Backtrace::Location)
  (3-1) name -> label
  (3-2) basename -> base_label (basename is confusing with
  File.basename)
  (3-3) line_no -> lineno (We have already similar name
  File#lineno, commented by kou [ruby-dev:45686]).
  (3-4) filename -> path.
  (3-5) filepath -> absolute_path.
  (3-5) iseq -> removed (we will make other APIs to access iseq
  and other information of frame for debugging).
* test/ruby/test_backtrace.rb: apply above changes.
  And apply comment from kou [ruby-dev:45686].
