Currently, Win JSC fails various ChakraCore tests due to diff failures.

The crux of the issue is that this works:
```
> .\WebKitBuild\Debug\bin64\jsc.exe .\JSTests\ChakraCore\test\jsc-lib.js .\JSTests\ChakraCore\test\Basics\bug650104.js
name: push -2885562136746910000number
undefined
Exception: TypeError: Number().push is not a function. (In 'Number().push()', 'Number().push' is undefined)
global code at .\JSTests\ChakraCore\test\Basics\bug650104.js:18:14
```
But if we add `> out.txt` to the end, the file contains just the first two lines and lacks the dumped exception.

The fix is simply to flush before exiting.
