[PATCH] D156491: [RA] Split a virtual register in cold blocks if it is not assigned preferred physical register

[Danila Malyutin via Phabricator via llvm-commits]

This patch also seems to cause near-infinite compile times in same cases (don't know if they actually finish as the process gets killed via OoM). Trying to get a reproducer now.
