UseAuto used to replace declarion lists with new expressons where some variable were not initialized with new. This fix checks that every DeclStmt has a VarDecl with an initializer and it also ensures that all declarations have the same type. Added tests for multiple declarations and for typedefs. llvm-svn: 182736
