All `go/types` data structures that expose sequences using a pair of
methods such as `Len() int` and `At(int) T` now also methods that
return iterators, allowing you to simplify code such as this:

```go
params := fn.Type.(*types.Signature).Params()
for i := 0; i < params.Len(); i++ {
   use(params.At(i))
}
```

to this:

```go
for param := range fn.Signature().Params().Variables() {
   use(param)
}
```
