score: Add _CPU_Context_switch_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 _CPU_Context_switch() to avoid generation of dead code in _Thread_Start_multitasking() if RTEMS was built with SMP support enabled.
