"[ES5 15.2 Object Objects] Mark with strict_mode_negative incompatible tests

Resolve incompatibilities with ES5. 

1) Eliminate unresolved variables. 

2) Test that tries to delete a property that has the attribute {
[[Configurable]]:false } should fail. (11.4.1)

#) Test that tries to write in a property with the attribute writable equal to false should fail.

Please hoist the var declaration outside the loop.  This may fool someone into
thinking that the var decl is scoped to the for-loop and it really isn't.

Why is this test strict mode negative?

> Why is this test strict mode negative?
This is how I interpreted: 

Object.prototype.isPrototypeOf is a function (15.2.4.6)

In line 19 the test try to change the value of the property "length" of the
isPrototypeOf function, that will lead to a [[PUT]] 

The property descriptor of "length" is: 
 {[[Value]]:len, 
  [[Writable]]: false, 
  [[Enumerable]]: false, 
  [[Configurable]]: false} (as specified at 13.2)

so the [[PUT]] action should lead to a TypeError Exception.

Am I making sense here? any wrong assumption?

You're exactly right - I was misreading writeable setting of isPrototype.length

LGTM

LGTM

Nit:
15.2.3_Properties_of_the_Object_Constructor/15.2.3.1_Object.prototype/S15.2.3.1_A3.js
has a spurious whitespace change at the top.
