Unpaired pointer-authentication hints (frame.pac_hints, GitHub #83): with VR running, Star Wars Pinball VR died with SIGILL ILL_ILLOPN at an autiasp (*pc=0xd50323bf) on Unreal's HttpManager thread: its libUE4.so has 38 paciasp but 40 autiasp (OpenSSL's Poly1305 NEON assembly). Quest CPUs run PAC hints as NOPs, the Frame's CPU checks them. In a library whose counts differ, every paciasp/autiasp becomes a NOP in place (libraries using retaa/pacibsp forms are left alone). Suggested by the new triage signature pac-unpaired
