Note that C restrict semantics make it necessary to properly track what
pointer is based on what other pointer.  For this we miss both annotations
and a (simple) propagator that propagates this information, maybe as part
of PTA analysis.

Note that the current implementation has both missed-optimization and latent
wrong-code issues.

(In reply to comment #3)
 Interestingly the following code is optimized:
That is because we create a new may_alias variable for malloc to point to so we
know that it cannot alias anything.
