[Sanjay Patel via Phabricator via llvm-commits]

Patch updated:

1. Improve hashing as suggested (I don't know how to expose that in a test, so no extra tests for that).
2. Add a "double-negation" matcher to recognize selects with same true/false ops but different conditions (positive and negative tests added).
