[Bug fortran/32800] New: ISO Bind C: C_F_Pointer argument bogus checking

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following fails if the FPTR argument is not the second argument.
The argument checking should be based on the ordered argument list not on the
position of the call ("FPTR=" is not always at the second position).

      CALL C_F_POINTER(FPTR=FPTR, CPTR=CPTR,SHAPE=[strlen(cptr)])
                                                                1
Error: Argument 'cptr' to 'c_f_pointer' at (1) must have the POINTER attribute



   FUNCTION C_F_STRING(CPTR) RESULT(FPTR)
      USE ISO_C_BINDING
      implicit none
