I'm not entirely sure we want to add them to debug builds, as it seems like a relatively expensive check to add to each call.

Possibly add ZEND_FUNC_INFO_DEBUG a la RC_DEBUG ?

This seems like the sort of thing we might want to enable when we're doing certain things, but not really all the time for any type of build - there'll be no ZEND_FUNC_INFO_DEBUG on CI I guess ordinarily, but we might want to enable it in a specific PR, or while we test a PR locally.
