[ProfInfo] Fix integer overflow in getDisjunctionWeights (#189079) 
This PR fixes an integer overflow in
[`getDisjunctionWeights`](https://github.com/llvm/llvm-project/blob/main/llvm/include/llvm/IR/ProfDataUtils.h#L241)
and adds a regression test to cover the failing case. Casting branch
weights before the computations solved the issue.
