This'd be FunctionCallInfoData not FmgrInfo.

I'm not terribly concerned about the size of FunctionCallInfoData,
but I am concerned about the number of cycles spent to initialize it,
because we do that pretty durn often.  So I don't really want to add
fields to it without compelling use-cases, and I don't see one here.
