  Changed paths:
    M libcxx/include/__functional/bind.h

  Log Message:
  -----------
  [libc++] Make std::allocator_arg and friends conforming in C++17

This patch makes global tag variables like std::allocator_arg
conform to C++17 by defining them as inline constexpr variables.
This is possible without creating an ODR violation now that we don't
define strong definitions of those variables in the shared library
anymore.
