Sorry about that, I didn't want to sound redundant after my previous
round of emails about build attributes... ;)

> Putting the build attributes on individual functions is not a good match for the final result, which is a single set of attributes for the entire object file.  If you put separate attributes on the functions, then code gen will have to scan all the functions to see if they have the same attribute values.
