Proposed patch: fix depend-iterator lowering for component arrays

The front end chose between scalar and array lowering based on the first
REF_ARRAY type, but for expressions like x(j)%a the first ref is the scalar
element x(j) while the full expression is still rank-1. This patch switches to
using the overall expression rank instead. Regtested on x86_64-pc-linux-gnu.
