_mjit_compile_send_guard.erb: carve out the shared logic to invalidate
inlined method call

common.mk: update dependency for this change

test_jit.rb: add test for attr_reader optimization

* Benchmark

```
require 'benchmark_driver'

Benchmark.driver do |x|
  x.prelude %{
    class C
      attr_reader :a
      def initialize
        @a = 1
      end
    end

    o = C.new

    def l o
      i = 0
      while i < 1000000
        o.a
        i += 1
      end
    end
  }
  x.report 'aread', %{ l o }
  x.loop_count 1000
