Subject: [PATCH] Change A9 scheduling itineraries VLD* / VST* entries default
 to "aligned". That is, it assumes addresses are 64-bit aligned (which should
 be the more common case). If the alignment is found not to be aligned, then
 getOperandLatency() would adjust the operand latency computation by one to
 compensate for it. rdar://9294833
