Well, "autoinit" was meant to mean "automated initialization."  But I 
take your point.  What would you say to "rs6000_init_generated_builtins"?

To be clear, this isn't new code.  It's just the only part of the old 
code that isn't replaced by the generated initialization. You'll see it 
repeated at the end of rs6000_init_builtins.  This is used on our port 
for adding one builtin from Darwin.  It's a standard macro, also used in 
the aarch64, i386, and netbsd ports.

Thanks for the review!  I'll commit after we agree on a name. (This will 
require minor changes to rs6000-gen-builtins.c to change the name of the 
generated function in rs6000-builtins.[ch].)
