Map type is scoped weirdly

[kevinjwz]

type myInt int

type myStruct struct {
	aaa map[myInt]myInt	// "map" scoped as "keyword.map.go"
}

var m1 map[myInt]myInt		// "map" scoped as "entity.name.type.go"
var m2, m3 map[myInt]myInt	// "map" scoped as "keyword.map.go"

func foo(arg map[myInt]myInt) {	// "map" scoped as "keyword.map.go"
}

Also, every "myInt" except the first one is simply scoped as "source.go".
