Thanks for your input Dave,
I think there is another way to avoid the stack overflow and reduce
the number of checks also,
Stack overflow will cause a problem only when we are backtracking the
last set of registers.
i.e when the difference between current SP and top of stack is less
than or equal

Altough stack overflow is expected in unwind_exec_insn, but in cases when area
beyond stack is not mapped to physical memory this can cause data abort.
To avoid above condition handle stack overflow in unwind_exec_insn by checking
vsp pointer from top of stack
