Owen Anderson cb21190cbd More Chris-inspired JumpThreading fixes: use ConstantExpr to correctly constant-fold undef, and be more careful with its return value. ...

This actually exposed an infinite recursion bug in ComputeValueKnownInPredecessors which theoretically already existed (in JumpThreading's
handling of and/or of i1's), but never manifested before.  This patch adds a tracking set to prevent this case.

Analysis

It is possible to try to merge a not-constant with a constantrage, when dealing with ptrtoint ConstantExpr's.
