vm_core.h: extract VM_STACK_OVERFLOWED_P

* vm_core.h (VM_STACK_OVERFLOWED_P, WHEN_VM_STACK_OVERFLOWED): extract
  condition from CHECK_VM_STACK_OVERFLOW.

* vm_exec.c (vm_stack_overflow_for_insn): move rb_bug call.

* vm_exec.h (CHECK_VM_STACK_OVERFLOW_FOR_INSN): share the condition
  with CHECK_VM_STACK_OVERFLOW.
