[Bug fortran/29657] New: Don't allow SAVE for functions

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

gfortran happily accepts the SAVE attribute for function (procedure attributes)

function sq(x)
  real, intent(in) :: x
  real, save :: sq  ! SAVE is wrong!
  sq = x**2
end function sq

g95:
Error: PROCEDURE attribute conflicts with SAVE attribute at (1)
sunf95:
ERROR: "SQ" is a function, therefore it must not be declared with the SAVE
attribute.
ifort:
The SAVE attribute conflicts with other declarations.
NAG f95:
Cannot SAVE procedure SQ
