Improve performance of rb_eql()

Browse source 
This improvement is similar with https://github.com/ruby/ruby/pull/1552

internal.h: add declaration of rb_eql_opt() API.

vm_insnhelper.c (rb_eql_opt): add rb_eql_opt() API which provides optimized
    path for #eql? method such as rb_equal_opt().

object.c (rb_eql): optimize using rb_eql_opt() such as rb_equal().
    Array#eql? and some methods have used rb_eql() and Array#eql? will be faster
    around 20%.

    [ruby-core:80761] [Bug #13447] [Fix GH-#1589]

### Before
       user     system      total        real
   1.570000   0.000000   1.570000 (  1.569754)

### After
       user     system      total        real
   1.300000   0.000000   1.300000 (  1.303624)

### Test code
require 'benchmark'

Benchmark.bmbm do |x|
  ary1 = Array.new(1000) { rand(1000) }
  ary2 = Array.new(1000) { rand(1000) }

  x.report do
    5000000.times do
      ary1.eql?(ary2)
    end
  end

end
