[PATCH] D67841: [SLP] avoid reduction transform on patterns that the backend can load-combine

[Sanjay Patel via Phabricator via llvm-commits]

spatel updated this revision to Diff 223625.
spatel added a comment.

Patch updated:
Moved "using PatternMatch" line within function that uses that API.

Side note: filed https://bugs.llvm.org/show_bug.cgi?id=43591 for larger questions about the cost model. I really don't want to hold up the underlying motivating bugs for this patch while we try to untangle that mess.
