* Add OperandToUndefReductionPass. Fixes #2115. Also added some tests that are similar to those in OperandToConstantReductionPassTest. In addition, refactor FindOrCreateGlobalUndef into reduction_util.cpp. Fixes #2184. Removed many documentation comments that were identical or very similar to the overridden function's documentation comment.
