I think we should abandon this patch and make -fsanitize=undefined work. undef can be mapped to a new bpf_fastcall kfunc no args and void return, so no extra register pressure and call can be inserted. That kfunc can eventually abort prog execution and print into upcoming per-prog trace_pipe (which we're adding to support deadlock reports, and aborts on page faults)
