After testing current mainline version of gadget scanner (with this stack of PRs applied) against llvm-test-suite, I spotted false positives for combined instructions like `retaa`: they were reported as authentication oracles, because `getAuthenticatedReg` returns LR for them, which is not checked afterward. As this is quite important issue to resolve before this PR is merged, I inserted #136147 before this PR and updated this one accordingly.
