Popping an element from an array should call [[Delete]] internal method
and pass true as the second argument (ECMA-262/5.1/#sec-15.4.4.6).
When the last element can't be deleted, throw a Type Error.
Not throwing the error would result in endless loop in the following test.

TEST=var a=[];Object.defineProperty(a,0,{});while(a.length)a.pop();

By the way fix another bug, or else i can't post any issues.
"presubmit.py" throw a "missing a correct copyright header" on windows.
Both the slash and the backslash are valid path separator on windows.

This change means that code which is never executed is garbage collected immediately, and code which is only executed once is collected more quickly (limiting heap growth), however, code which is re-executed is  reset to the young age, thus being kept around for the same number of GC generations as currently.

This is a part of https://codereview.chromium.org/26006004/.
These changes are enough to run most apps that embed V8 (by additionally
ignoring all memory accesses from V8), but don't help testing V8 itself in any
way.

This will be used by DevTools so that we could generate a better preview in console. Namely, we could assume that a preview of an object is lossless if all its member functions are builtin.

We also may want to expose this to DevTools users via remote debugging protocol in Debugger.FunctionDetails struct.
