Micro-benchmark for `value != nil` vs. `!value.nil?`

benchmark.rb

#!/usr/bin/env ruby

require 'benchmark'

Benchmark.bm do |b|
  n = 1_000_000

  value1 = 1
  value2 = nil

  b.report('value != nil') do
    n.times do
      value1 != nil
      value2 != nil
    end
  end

  b.report('!value.nil?') do
    n.times do
      !value1.nil?
      !value2.nil?
    end
  end
end

This should be a rubocop cop, shouldn't it?

@andreavocado it actually is! At first I didn't believe it would have improved the code, which is why I wrote the benchmark.
