score: Add _Thread_Dispatch_direct_no_return()
The __builtin_unreachable() cannot be used with current GCC versions to
tell the compiler that a function does not return to the caller, see:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99151
Add a no return variant of _Thread_Dispatch_direct() to avoid generation
of dead code.
