cmd/compile: do not add invalid key to constSet 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. For #43311 Fixes #44432 Change-Id: I44d8f2b95f5cb339e77e8a705a94bcb16e62beb9 Reviewed-on: https://go-review.googlesource.com/c/go/+/294034 Trust: Cuong Manh Le <cuong.manhle.vn@gmail.com> Run-TryBot: Cuong Manh Le <cuong.manhle.vn@gmail.com> TryBot-Result: Go Bot <gobot@golang.org> Reviewed-by: Matthew Dempsky <mdempsky@google.com>
