[PATCH] D60606: [SimpleLoopUnswitch] Implement handling of prof branch_weights metadata for SwitchInst

[Philip Reames via Phabricator via llvm-commits]

reames added a comment.

Two additional comments:

1. We appear to have the same lost profile problem for partial unswitching of branches.
2. When I wrote my early comment, I didn't realize this was sitting on top of proposed API changes.  I'd suggest focusing on the earlier patches, then wan return to this one.
