phiprop: Make sure types of the load match the inserted phi [PR122847]

This was introduced with r16-5556-ge94e91d6f3775, but the type
check for the delay was not happen because the type at the point
of delaying was set to NULL. It is only until a non-delayed load
when the phi is created, the type is set.

This adds the type check to the replacement for the delayed statements.

Pushed as obvious.
