Returning a pair instead of writing to two output parameters avoids a number of memory writes in the unrolled LEB-decoding slow path. Instead of writing to the length and result pointer after each byte, we now only write once at the very end. This makes the LEB decoding slow-path ~30% faster locally (but we do not spend much time in that function overall for most modules).
