  Changed paths:
    M libcxx/include/__support/ibm/xlocale.h

  Log Message:
  -----------
  [libc++] Provide c++03 alternative for va_copy if available in xlocale.h

Summary:
If we are on c++03 mode for some reason, and __builtin_va_copy is
available, then use it instead of error out on not having va_copy
in 03 mode.
