Because the Node AST represents references to declared objects (e.g., variables, packages, types, constants) by directly pointing to the referred object, we don't have use-position info for these objects. For switch statements with duplicate cases, we report back where the first duplicate value appeared. However, due to the AST representation, if the value was a declared constant, we mistakenly reported the constant declaration position as the previous case position. This CL reports back against the 'case' keyword's position instead, if there's no more precise information available to us. It also refactors code to emit the same "previous at" error message for duplicate values in map literals. Thanks to Emmanuel Odeke for the test case. Fixes #33460.
