Title: Optimize two_matrix_rows strategy for MRI

I put the check for RUBY_ENGINE inside the #default_strategy because i was not sure if you like the definition of 2 versions of #default_strategy with the check outside the method definition in order to get rid of the little performance impact of the check inside the method.

If you want it outside you can tell me to fix it.
