AddAutoStkpnt2

***********************************************
** Add automatical SP register change point
       arguments:       func_ea  - function start
                        ea       - linear address where SP changes
                                   usually this is the end of the instruction which
                                   modifies the stack pointer (cmd.ea+cmd.size)
                       delta    - difference between old and new values of SP
       returns: 1-ok, 0-failed

success AddAutoStkpnt2(func_ea, ea, sval_t delta);
