Hmm, I can't seem to find a function with that name. I guess a better name for this variable would be something like `IsPACOrEmuPACSupported` (EmuPAC being https://discourse.llvm.org/t/rfc-emulated-pac/85557), so we don't want to query whether PAC (the hardware feature) is supported in the current target.
