Title: new optimizer command: staticize non-virtual instance method

I added yet another optimizer command to JSX, which staticize non-virtual methods and eliminate runtime method lookup. We might change the name of this command because "staticize" is not very descriptive. Below are scores I measured with wasabiz/jsx-v8bench. The difference between them is apparently slight but I think this is enough good to merge.
