GetTickCount () is defined as returning the (possibly wrapped) number of
ms since the boot. Of course anyone who uses it to get the uptime is
stupid, but that doesn't mean we should not have a correct implementation
when possible. It's like not providing malloc() because someone may
misuse the pointer. A correct implementation is basically just two memory
loads more than the current (it would be enough to just store the
boot seconds, though), which is just noise performance-wise.
