e56faa9909 Add missing map check to optimized f.apply(...) 
This is a cutdown version of https://codereview.chromium.org/346473002/, which aimed to fix f.call and f.apply. Optimized f.call was removed by r21887, this is what was left.

7005abf03b Optimize Function.prototype.call 
- May inline the function, or call it directly, instead of going through call
- Supports arguments object escaping when it escapes to builtins (preparation for slice.call(arguments, ...) optimization)
- Both .call and .apply now support inlining when calling builtins indirectly

Avoid right shifts by zero bits: On ARM it actually means shifting by
32 bits (correctness issue) and on other platforms they are useless
(performance issue). This is fix for the fix in r20544.

509a1a405c ES6: Add support for values/keys/entries for Map and Set 
This allows code like this:

  var map = new Map();
  map.set(1, 'One');
  ...
  var iter = map.values();
  var res;
  while (!(res = iter.next()).done) {
    print(res.value);
  }
