[asan] Make GetCurrentThread RTEMS-friendly
On RTEMS, system and user code all live in a single binary and address
space. There is no clean separation, and instrumented code may
execute before the ASan run-time is initialized (or after it has been
destroyed).
Currently, GetCurrentThread() may crash if it's called before ASan
run-time is initialized. Make it return nullptr instead.
Similarly, fix __asan_handle_no_return so that it gives up rather than
try something that may crash.
