Original Commit Message:

    This is a reland of 800307f6, with a
    minimal fix for arm64 (uint64_t -> uintptr_t).

    Original change's description:
    > [wasm][memory64] Prepare Liftoff for ptrsize offsets
    >
    > This CL prepares the LiftoffAssembler interface for uintptr_t offsets.
    > Many places can still only handle 32-bit values, but after this CL we can
    > start storing the offsets as uintptr_t in the memory access immediates.
    > Some TODOs are placed to extend code generation for 64-bit additions, if
    > memory64 is enabled.
    > All of this will be addressed in follow-up CLs.
