[PATCH] D134951: [CodeGen] Propagate vreg flags to the regalloc spiller interface

[Quentin Colombet via Phabricator via llvm-commits]

Hi,

The `LiveIntervals` and `LiveRangeEdit` changes make sense to me (though in practice they are NFC.)

However, I'm not a fan of the MachineRegisterInfo change. Since it sounds like you need that field only for fast regalloc, could you do something specifically in that pass/with the related target hooks in that pass?

Cheers,
-Quentin
