__schedule_barrier intrinsic

This intrinsic creates a special sequence point that prevents operations with side effects from moving past it under all circumstances. Normal sequence points allow operations with side effects past if they do not affect program behavior. Operations without side effects are not restricted by the intrinsic, and the compiler can move them past the sequence point.

Unlike the __force_stores intrinsic, the __schedule_barrier intrinsic does not cause memory to be updated. The __schedule_barrier intrinsic is similar to the __nop intrinsic, only differing in that it does not generate a NOP instruction.
