Can you just use GET_MODE (mem) instead of
targetm.addr_space.address_mode (MEM_ADDR_SPACE (mem))
when you change plus_constant (mem, offset)?
At least, you should allow a backend to do

plus_constant (GET_MODE (mem), mem, offset)

instead of

mode = targetm.addr_space.address_mode (MEM_ADDR_SPACE (mem))

plus_constant (mode, mem, offset)
