  Log Message:
  -----------
  [flang] Avoid global name conflict when BIND(C,NAME=) is used

At the top level of program units in a source file, two subprograms
are allowed to have the same name if at least one of them has a
distinct interoperable binding name.  F18's symbol table requires
(most) symbols in a scope to have distinct names, though.  Solve
by using compiler-created names for the symbols of global scope
subprograms that have interoperable binding names.
