For looking at "dead stores" in declarations, we now check to see if the assigned value is a constant expression, e.g.: int x = 0; We then check to see if "x" is ever reassigned later. If so, we don't emit a warning. This is because programmers frequently use defensive programming to make sure a variable has a defined value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41853 91177308-0d34-0410-b5e6-96231b3b80d8
