Minitest::Benchmark#assert_performance_constant

Runs the given +work+ and asserts that the times gathered fit to
match a constant rate (eg, linear slope == 0) within a given
+threshold+. Note: because we're testing for a slope of 0, R^2
is not a good determining factor for the fit, so the threshold
is applied against the slope itself. As such, you probably want
to tighten it from the default.

See http://www.graphpad.com/curvefit/goodness_of_fit.htm for
more details.

Fit is calculated by #fit_linear.

Ranges are specified by ::bench_range.

Eg:

  def bench_algorithm
    assert_performance_constant 0.9999 do |n|
      @obj.algorithm(n)
    end
  end
