Andrew Trick 204494149b Move replaceCongruentIVs into SCEVExapander and bias toward "expanded" ...

IVs.

Indvars previously chose randomly between congruent IVs. Now it will
bias the decision toward IVs that SCEVExpander likes to create. This
was not done to fix any problem, it's just a welcome side effect of
factoring code.
