f5cd181f - [Coverage] Introduce `getBranchCounterPair()`. NFC. (#112702)

[Coverage] Introduce `getBranchCounterPair()`. NFC. (#112702) This aggregates the generation of branch counter pair as `ExecCnt` and `SkipCnt`, to aggregate `CounterExpr::subtract`. At the moment: - This change preserves the behavior of `llvm::EnableSingleByteCoverage`. Almost of SingleByteCoverage will be cleaned up by coming commits. - `IsCounterEqual(Out, Par)` is introduced instead of `Counter::operator==`. Tweaks would be required for the comparison for additional counters. https://discourse.llvm.org/t/rfc-integrating-singlebytecoverage-with-branch-coverage/82492
