(If no anonymous args follow, the result of list_length is actually
one too large. This is harmless.)
If PRETEND_OUTGOING_VARARGS_NAMED is set and STRICT_ARGUMENT_NAMING is
zero, this machine will be able to place unnamed args that were
passed in registers into the stack. So treat all args as named.
This allows the insns emitting for a specific argument list to be
independent of the function declaration.
