[PATCH] D151227: RFC: LiveIntervalCalc: Always split separate components

[Quentin Colombet via Phabricator via llvm-commits]

> Right, it does complain about the LiveIntervals, but I thought that indicated that the LiveIntervals were not computed correctly, not that the underlying MIR was malformed.

Fair point. I guess we're back to your original question: can the compiler actually produce this kind of MIR that happens to be ill-formed for LiveIntervals computation?

I don't believe it can, but if fixing that makes our life easier (e.g., by unblocking some `llvm-reduce` workflow) without noticeable compile time impact, I think we should do it.
