llvm/test/Transforms/InstCombine/cast.ll
Sanjay Patel 36ff41aa37 [InstCombine] remove fold of an icmp pattern that should never happen 
While removing a scalar shackle from an icmp fold, I noticed that I couldn't find any tests to trigger
this code path.

The 'and' shrinking transform should be handled by InstCombiner::foldCastedBitwiseLogic()
or eliminated with InstSimplify. The icmp narrowing is part of InstCombiner::foldICmpWithCastAndCast().
