Ok, the assertion was bogus. Calls that do not read/write memory should not
...
have an alias set, just like adds and subtracts don't.

Add a new AliassetTracker::remove method. Because we need to be able to remove
...
a pointer from an AliasSet, maintain the pointer values on a doubly linked
list instead of a singly linked list, to permit efficient removal from the
middle of the list.

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.

revision as I start to use it though.
