FunctionObject: Mark name/length property configurable

In ES5, these were not configurable, but ES6 changed the behavior.

For length, refer to:
    9.2.4 (FunctionInitialize)
    17 (ECMAScript Standard Built-in Objects):
        Unless otherwise specified, the length property of a built-in Function
        object has the attributes { [[Writable]]: false, [[Enumerable]]: false,
        [[Configurable]]: true }.
    19.2.2.1 Function.length
    19.2.3.2 (Function.prototype.bind)
    19.2.4.1 (Function instances, length)

For name, refer to:
    9.2.11 (SetFunctionName)

This does regress test262 for ES5 for me a little, but improves our es6 test
coverage a bit (~682 more tests pass, +1.5%).
