Upgrade benchmark-ips to 2.11.0

What does this MR do and why?

Now hold! and save! can be used to compare independent invocations.

Example

require "benchmark/ips"

p n_('day', 'days', 0)
p n_('day', 'days', 1)
p n_('day', 'days', 2)

Benchmark.ips do |x|
  FastGettext::MoFile.prepend(MoFilePatchFast) if ENV['FAST']

  x.report "plural #{ENV['FAST'] ? 'fast' : 'slow'}" do
    n_('day', 'days', 1)
  end

  x.save! 'fast_gettext' # <--- NEW 
  x.compare!
end
