[PATCH] D108837: [SimplifyCFG] Ignore free instructions when computing cost for folding branch to common dest

[Piotr Padlewski via Phabricator via llvm-commits]

Prazek added a comment.

This looks resonable. BTW are `{launder,strip}.inariant.group` intrinsics considered to be free now?  I remember fixing this in InlineCost, but this seems to be other cost heuristic.  They totally should be considered free.
