Owen Anderson 18e816f356 Switch to a very conservative heuristic for determining when loop-unswitching 
will be profitable.  This is mainly to remove some cases where excessive
unswitching would result in long compile times and/or huge generated code.

Once someone comes up with a better heuristic that avoids these cases, this
should be switched out.

Andrew Lenharth ebfa24ee9a Catch more function pointer casting problems 
Remove the Function pointer cast in these calls, converting it to
a cast of argument.
%tmp60 = tail call int cast (int (ulong)* %str to int (int)*)( int 10 )
%tmp60 = tail call int cast (int (ulong)* %str to int (int)*)( uint %tmp51 )

Chris Lattner 90213c6c18 Handle alias sets that have been unified, and thus can have other references 
to them.  This fixes a regression in my previous checkin.

Chris Lattner f4e0653b3a Don't implement AliasSetTracker::remove in terms of deleteValue. deleteValue 
causes the pointer to be removed from the underlying alias analysis
implementation as well.  This impl of remove is also significantly faster than
the old one.  This fixes:
