[IA64] Reschedule __kernel_syscall_via_epc(). Avoid some stalls, which is good for about 2 cycles when invoking a light-weight handler. When invoking a heavy-weight handler, this helps by about 7 cycles, with most of the improvement coming from the improved branch-prediction achieved by splitting the BBB bundle into two MIB bundles.
