[PATCH] D88020: [SplitKit] In addDeadDef tolerate parent range that defines more lanes

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

I don't think it's safe to add dead defs to the extra lanes.  You could split the superset into the matching part and the remaining part, then only operate on the matching one.
