I favour trying to fix most of the issues to get us to a baseline of
(ideally) all xc files equal between host compilers, or at least a small
number of known not-equal ones, and then making systematic changes like
this.  It's just too easy to regress otherwise.  Once we're done or
close to done, it might be more obvious which of the cl/xc gensyms is
most useful.
