As far as I see, there are two places where `emitPtrauthDiscriminator` is
called with `/*MayUseAddrAsScratch=*/true`: `emitPtrauthBranch` and
`emitInstruction` for `AUTH_TCRETURN`/`AUTH_TCRETURN_BTI`. Are both cases
tested? It looks like that this new test case is designed for signed tail call
which covers only one of two code paths, doesn't it?
