score: Do not inline _Thread_Dispatch_enable()
This function is slighly too complex for inlining with two if
statements. The caller already needs a stack frame due to the potential
call to _Thread_Do_dispatch(). In _Thread_Dispatch_enable() the call to
_Thread_Do_dispatch() can be optimized to a tail call.
