eval('[__FILE__, __LINE__]') will not work in future Ruby.
Let's stop using it when Binding#source_location is available because it
prints noisy warnings.
Since Binding#source_location is added in Ruby 2.6
https://github.com/ruby/ruby/commit/571e48b7442, this commit is leaving
old code with branching by binding.respond_to?(:source_location).
Fixes #1871
