14ac877e0a - Checkin of the alias analysis work: 
* Takes into account the size of the memory reference to determine aliasing.
    * Expose mod/ref information in a more consistent way
    * BasicAA can now disambiguate A[i][1] and A[j][2] for conservative request
      sizes

9971ac4a36 This is a substantial rewrite of the AliasSetTracker class which now uses 
a union-find based algorithm, is significantly faster, and is more general.
It will also scale to handle call instructions correctly, which is a nice
added bonus.

This includes a new pass -print-alias-sets which can be used to show how
alias sets are formed for a particular analysis.
