    M flang/runtime/unit.cpp
    M flang/runtime/unit.h

  Log Message:
  [flang][runtime] Catch & report attempts at recursive I/O

When an I/O statement contains a function call that attempts
to perform I/O on the same unit, detect the recursive I/O
and terminate with a useful message rather than deadlocking in
the threading library.
