After CL 272654, the compiler now use go/constant.Value to represent constant nodes. That makes ir.ConstantValue requires node type to correctly return value for untyped int node. But untyped int node can have nil type after typechecked, e.g: using int value as key for map[string]int, that makes the compiler crashes. To fix it, just don't add the invalid key to constSet, since when it's not important to report duplicated keys when they aren't valid.
