[PATCH] D44564: [BasicAA] Relax restriction on PHI node handling.

Hmm.  I don't see anything wrong with the code, but how often will this trigger?  instcombine will remove the PHI nodes in your testcase, so this is only a problem if you have a pass which creates PHI cycles like this.  I guess GVN does in some cases?  Can we avoid doing that?
