I think between the existing ‘getBranchWeights’ and the ‘getNumBranches’ in
https://github.com/llvm/llvm-project/pull/90146 we should be able to avoid most
issues.
Ideally, the only place that should be setting the operand directly would be
things in this file.
Let me take a pass over the existing users outside of this file to see if there
is a way to do that.
