[PATCH] D158668: Add getLikelyBranchWeight helper function

[Matthias Braun via Phabricator via cfe-commits]

MatzeB added a comment.

And as another strawman / discussion-started I put up D158680 <https://reviews.llvm.org/D158680> where I use `!{"branch_weights", i32 1, i32 0}` to represent likely branches and the actual "LikelyWeight" mostly becomes an internal implementation detail of the BranchProbabilityInfo class... This seemed like a neat way to get an abstract "likely", "unlikely" notation, but not sure of the effects if we no longer would have "truly zero" weights because they would be interpreted differently now...
