Do not replace variable op variable in I/O implied DO loop replacement.
This PR came about because index expressions of the form k+k in
implied DO loops in I/O statements were considered for replacement
by array slices.
Fixed by only doing the transformation if the expression is of the
type expr OP contastant.

PR fortran/100227
* frontend-passes.c (traverse_io_block): Adjust test for
when a variable is eligible for the transformation to
array slice.
