should not indirect nil

[ltzmaxwell]

Example:

package main

func main() {
	println(*nil)
}

Output:

panic: runtime error: invalid memory address or nil pointer dereference [recovered]
	panic: runtime error: invalid memory address or nil pointer dereference:
	--- preprocess stack ---
	stack 2: func main() { (const (println func(xs ...interface{})()))(*((const (undefined)))) }
	stack 1: file{ package main; func main() { (const (println func(xs ...interface{})()))(*((const (undefined)))) } }
	stack 0: package(main)

Expected Output:
invalid operation: cannot indirect nil.
