i32.store8, i64.store8, i64.store32, v128.store and v128.storeN_lane computed the effective address with wrapping int arithmetic, so an address + offset >= 2^32 wrapped to a low in-bounds address and the store succeeded instead of trapping. Route them through readMemPtr like every other load and store.
