VM never extends vp->sp beyond mapped region of stack

* libguile/vm-engine.c (ALLOC_FRAME): Fold CHECK_OVERFLOW into this
  routine, and rework to not extend vp->sp until the stack has been
  expanded.

* libguile/vm.c (vm_increase_sp): Likewise, don't extend vp->sp until
  the stack has expanded.
  (vm_expand_stack): Rework to take the new stack pointer as an
  argument, and also to update vp->sp_max_since_gc and vp->sp.
