[Bug fortran/32159] New: Explicit-typing of intrinsic functions: print warning

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

For following program a warning should be printed. NAG f95 prints:
Warning: yy.f90, line 9: Type declaration for generic intrinsic LEN ignored

If one changes "real :: len" into "integer :: len", NAG f95 shows:
Warning: yy.f90, line 9: Intrinsic function LEN explicitly typed

I think it makes sense to have the first warning always shown. For the second
one, maybe only with -W* ?

PROGRAM VAL
implicit none
integer :: i
real :: len
intrinsic :: len
i = len(" ")
END
