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.

- 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.
