That worked, and allowed me to do a bootstrap on x86_64 for all languages and
regtest for unix/ and unix/-m32 without any issues (other than scan-dump-tree
failures for stdarg, since the va_list_gpr/fpr_size optimization is switched off).
That leaves just teaching the va_list_gpr/fpr_size optimization to recognize
ifn_va_arg.
