    M clang/lib/AST/ExprConstant.cpp
    M clang/test/SemaCXX/builtins.cpp
    M clang/test/SemaCXX/constant-expression-cxx11.cpp

  Log Message:
  -----------
  Improve diagnostic for an expression that's not constant because it uses
the address of a constexpr local variable.

Suggest adding 'static' to give the constexpr local variable a constant
address.
