Use the new asan:stack statement
This allows us to account for the stack on the memory report. Using half
of the $100 page for stack management is most surely overblown, but I
have not really computed how much we are using the stack on this game,
even if I suspect that its usage is actually pretty minimal. Anyways, we
have room to spare in RAM space, so let's reserve half a page for the
stack.
