When the packetizer wants to put a store to a stack slot in the same
packet with an allocframe, it updates the store offset to reflect the
value of SP before it is updated by allocframe. If the store cannot
be packetized with the allocframe after all, the offset needs to be
updated back to the previous value.

In all but one case, change the DFAPacketizer API to take MachineInstr&
instead of MachineInstr*. In DFAPacketizer::endPacket(), take
MachineBasicBlock::iterator. Besides cleaning up the API, this is in
search of PR26753.

Change TargetInstrInfo API to take `MachineInstr&` instead of
`MachineInstr*` in the functions related to predicated instructions
(I'll try to come back later and get some of the rest). All of these
functions require non-null parameters already, so references are more
clear. As a bonus, this happens to factor away a host of implicit
iterator => pointer conversions.
No functionality change intended.
