Axiom loadbytes_store_same:

loadbytes m2 b ofs (size_chunk chunk) = Some(encode_val chunk v).
Axiom loadbytes_store_other:
forall chunk m1 b ofs v m2, store chunk m1 b ofs v = Some m2 ->
forall b' ofs' n,
b' <> b \/ n <= 0 \/ ofs' + n <= ofs \/ ofs + size_chunk chunk <= ofs' ->
loadbytes m2 b' ofs' n = loadbytes m1 b' ofs' n.
