[PATCH] D158668: Add getLikelyBranchWeight helper function

[Matthias Braun via Phabricator via cfe-commits]

MatzeB added a comment.

Putting this out as a strawman/RFC. Should we add this function to allow LLVM passes to construct "likely"/"unlikely" branch_weights metadata? (I need this in D158642 <https://reviews.llvm.org/D158642> and D157462 <https://reviews.llvm.org/D157462>)
