* variable.c (rb_alias_variable): should not allow variable
aliasing if $SAFE >= 4.
* parse.y (expr): "break" and "next" to take optional expression,
which is used as a value for termination. [new, experimental]
* eval.c (rb_eval): "break" can give value to terminating method.
* eval.c (rb_eval): "break" and "next" to take optional expression.
* eval.c (rb_yield_0): "next" can give value to terminating "yield".
* eval.c (rb_iterate): "break" can give value to terminating method.
* eval.c (proc_call): ditto.
