From investigation of a few slow analysis cases, I discovered that `RegionStoreManager::bind*` and `ExprEngine::removeDead` are often the slowest actions. This change adds explicit scope to the time trace generated by `-ftime-trace` to enable easy diagnostics of the cases when these functions are the slowdown culprits. -- CPP-6109
