[PATCH] D106408: Allow rematerialization of virtual reg uses

[Vasileios Porpodas via Phabricator via llvm-commits]

vporpo added a comment.

Just to add that this patch caused a huge compilation time increase in some workloads, with the majority of time spent in `eliminateDeadDefs()` called by `rematerializeAll()`. The compilation time regression was gone after this patch was reverted.
