4eaaa99b93 Convert LICM over to use AliasSetTracker. Besides being nicer, this automatically 
allows LICM to use access sizes to help alias analysis be more precise.

74b9aaa89c 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.

    successors.  See bug: LICM/2003-02-27-PreheaderProblem.ll

b078b28fa5 * 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

a84b1da40f - 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
