Instead of just printing the value, print the original node to make the error more human-friendly. Also print the value if its string form is different than the original node, to make sure it's obvious what value was duplicated. This means that "case '@', '@':", which used to print: duplicate case 64 in switch Will now print: duplicate case '@' (value 64) in switch Factor this logic out into its own function to reuse it in range cases and any other place where we might want to print a node and its value in the future. Also needed to split the errorcheck files because expression switch case duplicates are now detected earlier, so they stop the compiler before it gets to generating the AST and detecting the type switch case duplicates. Fixes #20112.
