Also adds a test file to verify thesewarnings.This warning would not happen since the -Wsign-conversion would make adiagnostic then return, never allowing the -Wenum-conversion checks.For example:Cenum PE { P = -1 };enum NE { N };enum NE conv(enum PE E) { return E; }Before this would only create a diagnostic with -Wsign-conversion andnever on -Wenum-conversion. Now it will create a diagnostic for both-Wsign-conversion and -Wenum-conversion.I could change it to just warn on -Wenum-conversion as that was what Iinitially did. Seeing PR35200 (or GitHub Issue 316268), I let bothdiagnostics check so that the sign conversion could generate a warning.
