[PATCH] D35229: [CodeGen] Add support for instruction clusters

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

I'm not sure I like this:

- It introduces a new word "cluster", so we end up having the words "MacroFusion" and "Cluster" around which appear to mean the same thing?
- Using `computeOperandLatency()` to compute something called cluster feels out of place, similar with getReadAdvanceCycles
