Hi, I think this can wait for 4.5. What's other reviewers' opinion?

Hum, we will forget about it, so we should remove them now.
Or if it breaks too much, the common code between gfc_simplify_reshape
and gfc_check_reshape should be shared (calling gfc_check_reshape from
gfc_simplify_reshape is probably enough) so that any fix/improvement
made for one function also affects the other.
