Arnold Schwaighofer 5940796cc1 SIL: Add an is_escaping_closure instruction
Will be used to verify that withoutActuallyEscaping's block does not
escape the closure.

``%escaping = is_escaping_closure %closure`` tests the reference count. If the
closure is not uniquely referenced it prints out and error message and
returns true. Otherwise, it returns false. The returned result can be
used with a ``cond_fail %escaping`` instruction to abort the program.
