[Bug fortran/44960] New: non-array used as an array, identified as an external function

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

Spin-off from PR43179:

type t
  integer :: a
end type t
type(t) :: foo
! external :: foo          ! "Syntax error in PRINT"
print *, foo(1)%a
end

foo is used as an array although no declared as one; gfortran takes it as an
external function, although one can not access components of returned types
directly from the function call as it would be possible in C. The latter is
picked up if foo is confirmed as EXTERNAL function.

Expected: either error-out on component access on function return value or
deduce that it can not be function and must be an array - and error out as it
is not declared as one.
