countBodyLenAfterFixupsExtraRefs

Return the number of instructions in body after prepending the ref instructions in ref_table. As well as all instructions in body, we also prepend refs of any instruction in extra_refs. For instance, if an index has been reserved with a special meaning to a child block, it must be passed to extra_refs to ensure refs of that index are added correctly.
