I don't know whether you're being facetious, but IMHO avoiding
function call overhead is not a good argument for making a piece of
code a macro instead of a function.  I've seen many circumstances
where macros (or inlined functions) decrease the overall performance
of a system because the added code results in i-cache thrashing.

I think we should be addressing performance problems that are the
result of poor algorithms rather than spending any time bothering
with microoptimizations.
