Jan Wen Voung 1a63641597 Fix ARM peephole optimizeCompare to avoid optimizing unsigned cmp to 0. 
Summary:
Previously it only avoided optimizing signed comparisons to 0.
Sometimes the DAGCombiner will optimize the unsigned comparisons
to 0 before it gets to the peephole pass, but sometimes it doesn't.

Fix for PR22373.
