Invalid output by secilc with constraints containing 4 nested OR and a single AND

[bauen1 <j2468h@xxxxxxxxxxxxxx>]

Hello,
I've discovered that a constraint like

(constrain (file (open))
  (or
    (eq t1 exec_t) ; probably doesn't matter
    (or
      (eq t1 exec_t) ; probably doesn't matter
      (or
        (eq t1 exec_t) ; probably doesn't matter
        (or
          ; Making and the first argument to or will produce a valid policy
          (eq t1 exec_t)
          (and
            ; content probably doesn't matter
            (eq t1 exec_t)
            (eq t1 exec_t)
          )
        )
      )
    )
  )
)

allows secilc to finish compilation but generates a policy that is "invalid", file identifies it as an SELinux Binary Policy but seinfo and similiar tools refuse to operate on it.

For example (using secilc/test/policy.cil):
$ file policy.32 
policy.32: SE Linux policy v32 8 symbols 9 ocons
$ seinfo policy.32 -x --constrain
Invalid policy: policy.32. A binary policy must be specified. (use e.g. policy.32 or sepolicy) Source policies are not supported.

I've tested this with secilc 3.1-1 (debian) and from the current git master (9e2b8c61bfd275d0f007a736721c557755edf4a0)

I hope that this is enough information to reproduce the issue.
