    middle-end/99281 - avoid bitfield stores into addressable types

    This avoids doing bitfield stores into the return object of calls
    when using return-slot optimization and the type is addressable.
    Instead we have to pass down the original target RTX to the call
    expansion which otherwise tries to create a new temporary.

            * expr.c (store_field): For calls with return-slot optimization
            and addressable return type expand the store directly.
