Feature #9755: Thread::Backtrace::Location#defined_class

I'd like Thread::Backtrace::Location#defined_class.

class X
  def foo
    p caller_locations.first.defined_class #=> Y
  end
end

class Y
  def bar
    X.new.foo
  end
end

Y.new.bar

nobu created a patch:

https://github.com/nobu/ruby/compare/backtrace-self%2Bclass

But this patch has two problems:

1. The patch adds Thread::Backtrace::Location#self, but it's weird that a location has self.
2. Thread::Backtrace::Location#class conflicts with Kernel#class.
   So I proposed defined_class as the method name.
