Subject: [PATCH] Bytes: only the vec repr is not shared (#100)
The shared debug_assert is to ensure that the internal Bytes
representation is such that offset views are supported. The only
representation that does not support offset views is vec.
Fixes #97

// Only run these tests on little endian systems. CI uses qemu for testing
