'profile has merged rule with conflicting x modifiers' with change_profile /**

[Jamie Strandboge]

The parser is inconsistently applying the conflicting x modifier check when using 'change_profile /**':

$ cat ./apparmor.profile
#include <tunables/global>
profile test {
  #change_profile unsafe /** -> *, # conflicts
  change_profile /** -> *, # conflicts
  change_profile -> *, # does not conflict

  @{HOME}/[^s.]** ix, # conflicts
  @{HOME}/** ix, # does not conflict
}

$ apparmor_parser -QTK ./apparmor.profile
profile has merged rule with conflicting x modifiers
ERROR processing regexs for profile test, failed to load
[1]

I would expect either both of the @{HOME} rules to conflict or both to not conflict (though it seems like they should not conflict since the ix rule is a more specific match, but that is a different issue).
