Improve performance of rb_eql()
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%.

### 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
