[Sema] Emit a better diagnostic when variable redeclarations disagree We referred to all declaration in definitions in our diagnostic messages which is can be inaccurate. Instead, classify the declaration and emit an appropriate diagnostic for the new declaration and an appropriate note pointing to the old one. This fixes PR24116. llvm-svn: 242190
