Mishandling of type redeclaration

[mvertes]

The following valid Go code fails with gno:

package main

type (
	Number  = int32
	Number2 = Number
)

func f(n Number2) { println(n) }

func main() {
	var n Number = 5
	f(n)
}

// Output:
// 5

See also the following variant of the same problem:

package main

type Number = int

func main() {
	println(Number(1) < int(2))
}

// Output: true
