That makes sense (given that we already have some ptrauth-*.ll tests), thanks for suggestion. Renamed in bc3ae2a0a1a8689a9487b323d18f68b34f5d5dc9

As for this PR, ptrauth-*.ll tests just duplicate corresponding non-pauth tests. I suppose that if we want to change how tests are organized, this should be done separately in order not to mix functional and refactoring changes.
