Class contructor and methods shouldn't have "arguments" and "caller"

Summary Class contructor and methods shouldn't have "arguments" and "caller"

Apparently ES6 gutted "arguments" property from class constructors and methods. Authors should also be able to define a property named "arguments"; e.g. class A { static arguments() {} } class B { static get arguments() {} }

I think define arguments property should be fixed in separate patch, we already has one https://bugs.webkit.org/show_bug.cgi?id=152985
