[PATCH] D32661: Remove stale live-ins in the branch folder

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz created this revision.

Hoisting common code can cause registers that live-in in the successor blocks to no longer be live-in. The live-in information needs to be updated to reflect this, or otherwise incorrect code can be generated later on.
