Feel free to ignore: it's probably worth having a more specific error message here. It's not actually obvious why we are erroring out - is this because signing function pointers with non-zero offsets is not supported? Even if we leave this error message as is, it's probably worth at least having a comment here (and in clang/test/CodeGen/ptrauth-function-init.c as wel)
