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

[Christudasan Devadasan via Phabricator via llvm-commits]

cdevadas added a comment.

> 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?

The alternative would be to pass the flags as an argument to the target hooks storeRegToStackSlot & loadRegFromStackSlot which are common to both fast regalloc and greedy.
