The problem is basically that early on during the init process in the iOS simulator, `sysctlbyname` gets called and we intercept it but this triggers a call to `__cxa_atexit` inside TSan's init process but the library implementing `__cxa_atexit` hasn't been initialized yet.

@devnexen I have a potential fix up for review at https://reviews.llvm.org/D55711
