7e7ad49c23 Add a new assertion to check that stuff is happening right 
Ironically the exit block modification code wasn't updating the exit block
information itself.  Fix this.

dbf3cd7952 * Significant changes to the preheader insertion pass: 
- Now we perform loop exit-block splitting to ensure exit blocks are
     always dominated by the loop header.
   - We now preserve dominance frontier information
   - This fixes bug: LICM/2003-02-26-LoopExitNotDominated.ll

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.
