  Log Message:
  -----------
  [flang] Warn about dangerous TRANSFER()

When the source or mold of a reference to the intrinsic function TRANSFER()
has a derived type with a direct component that contains a descriptor,
such as an allocatable or a pointer, emit a warning.  User programs
should never access descriptors directly.
