Patch updated:

1. Converted getOneTrueElt() into a lambda.
2. Added TODO comment about hoisting this to DAGCombiner.
3. Added TODO comment about supporting other mask types (but if we do, what is the format for those masks?)
4. Added test cases to demonstrate extraction from different types, high elements, and different sizes of vectors.
