[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.
