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.

5f07a8b312 - Eliminate provably non-pointer nodes from graphs.
This helps a lot of testcases, for example:
            New Time  New #Nodes     Old Time    Old #Nodes
254.gap:    91.1024     21605        91.1397     22657
povray31:    2.7807      8613         3.0152     10338
255.vortex:  1.2034      8153         1.2172     8822
moria:        .6756      3150          .7054     3877
300.twolf:    .1652      2010          .1851     3270

Typically, testcases which use long and ulong integers a lot get better, f.e. povray above.
