[PATCH] D45308: [IPRA] Do not collect register usage information on functions that can be derefined

Created a new function (isSafeForIPRA) to consistently check whether IPRA can be performed. This check is used in RegUsageInfoCollector as well as isSafeForNoCSROpt. I also went back to the original checks in isSafeForNoCSROpt to check for LocalLinkage.
