After the default implementation swap from https://github.com/llvm/llvm-project/pull/117493, where `areInlineCompatible` checks if the callee features are a subset of caller features. This is not a safe assumption in general on PPC. We fallback to check for strict feature set equality for now, and see what improvements we can make.
