[Bug middle-end/30798] mode_dependent_address_p not checked when simplifying subreg

By the way, I think emit-rtl.c: change_address_1 could at least use an assert
that if the modes are different and the addresses are the same, then
mode_dependent_address_p is not true.  That is unless change_address_1 can be
used to change the semantics of a mem.
