[llvm] IR: fix getSwappedCmpPredicate() return type (PR #120097)

[Ramkumar Ramachandra via llvm-commits]

https://github.com/artagnon created https://github.com/llvm/llvm-project/pull/120097

The change 51a895a (IR: introduce struct with CmpInst::Predicate and samesign) missed a change to ICmpInst::getSwappedCmpPredicate(), which intends to return a CmpPredicate, but returns a Predicate instead. Fix this.
