As noted in the Cauldron Discussion I think you should do all instrumentation
post-IPA only to simplify your life not needing to handle inlining of
instrumentation
and to get the full benefit of WPA analysis when used with LTO.  That might
even mean doing it as a regular IPA pass where clones are used for strubbing
and original bodies are used for inlining.
