[PATCH] D45366: Support generic expansion of ordered vector reduction (PR36732)

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon updated this revision to Diff 141374.
RKSimon added a comment.

Cleaned up based on @ABataev's comments.

@aemerson explained on https://reviews.llvm.org/D45336 that the strict/ordered reductions should always use the accumulator argument, so I've removed the is null or undef logic.
