Proposal: allow super in object literals

Description

obj1 = ->
  method1: ->
    console.log 'method1'

obj2 =
  method2: ->
    super.method1()

Object.setPrototypeOf obj2, obj1
obj2.method2() # logs "method1"

obj2 = {
  method2() {
    super.method1();
  }
};

Research direction

Examine the CoffeeScript compiler source, likely in 'lib/coffee script/parser.coffee' or similar, to understand how method definitions are currently transpiled. Review the issue comments for any discussion on implementation approaches. Consider how `super` is handled in class methods and extend to object literal methods. The proposal requires adding support for `super` in shorthand method definitions in object literals.
