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.

e1d4fb3c2c Fix bug: LICM/2003-02-27-PreheaderProblem.ll
There may be a single outside predecessor and
still need a new loop-preheader if the predecessor has multiple
successors.

e8dda81b22 * Don't forget to update Loop information!

    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

      sizes

f2009dbddb 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.
