Summary: Check if the first eligible callee is under the instruction threshold. Checking this on the first eligible callee ensures that we don't end up selecting different callees to import when we invoke this routine with different thresholds due to reaching the callee via paths that are shallower or hotter (when there are multiple copies, i.e. with weak or linkonce linkage). We don't want to leave the decision of which copy to import up to the backend.
