/* StackProbe -- probe above the stack to provoke early stack overflow
*
* This function should check that the stack has at least depth words
* available, and if not, then provoke a stack overflow exception or
* protection fault. The purpose is to ensure that the exception is
* generated before taking the arena lock where it can be handled
* safely, rather than at some later point where the arena lock is
* held and so handling the exception may cause the MPS to be entered
* recursively.
