[PATCH] D33088: [LiveVariables] Switch Kill/Defs sets to be `DenseSet`

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

And also slightly related: For the sort of queries that LiveVariables supports "Fast liveness checking for ssa-form programs" / https://doi.org/10.1145/1356058.1356064 would be a perfect fit. However given that the long term goal would be to replace all of this with LiveIntervalAnalysis, it's probably not worth pursuing that here.
