Summary: This fixes the `ThreadSanitizer-x86_64-iossim` testsuite which broke when r348770 (https://reviews.llvm.org/D55473) landed. The root cause of the problem is that early-on during the iOS simulator init process a call to `sysctlbyname` is issued. If the TSan initializer is triggered at this point it will eventually trigger a call to `__cxa_at_exit(...)`. This call then aborts because the library implementing this function is not yet had its initialization function called. rdar://problem/46696934 Reviewers: kubamracek, george.karpenkov, devnexen, vitalybuka, krytarowski Subscribers: #sanitizers, llvm-commits Differential Revision: https://reviews.llvm.org/D55711 llvm-svn: 349402
