fs: don't segfault on deeply recursive stat()
Check that the calls to Integer::New() and Date::New() succeed and bail out if they don't. V8 returns an empty handle on stack overflow. Trying to set the empty handle as a property on an object results in a NULL pointer dereference in release builds and an assert in debug builds. Fixes nodejs#4015.
