[PATCH] D78686: [PowerPC] Fix downcast from nullptr

Thanks for the advice, Steven. I found some existing tests that exercised the particular downcasting logic, and found that if I set -filetype=null in those RUN: directives, I could trigger a crash. So I added a line to those tests. Also made the same fix to PPCAsmParser and PPCAIXAsmPrinter.
