The TLS implementation on apple platforms has changed. Instead of invoking pthread_getspecific with a pthread_key_t, we instead perform a virtual function call.
Note: Some versions of Apple's new linker do not emit debug symbols for TLS symbols. This causes the TLS tests to fail because LLDB and dsymutil expects there to be debug symbols to resolve the relevant TLS block. You may work around this by switching to the older linker (ld-classic) or by disabling the TLS tests until you have a newer version of the new linker.
