Auto merge of #101442 - joboet:null_check_tcs, r=thomcc
Check if TCS is a null pointer on SGX The `EENTER` instruction only checks if the TCS is aligned, not if it zero. Saying the address returned is a `NonNull<u8>` (for which `Tcs` is a type alias) is unsound. As well-behaved runners will not put the TCS at address zero, so the definition of `Tcs` is correct. However, `std` should check the address before casting it to a `NonNull`. ping `@jethrogb` `@raoulstrackx` `@rustbot` label I-unsound
