Detailed Description
TLB TranslationState: this currently is a somewhat bastardization of the usage of SenderState, whereby the receiver of a packet is not usually supposed to need to look at the contents of the senderState, you're really only supposed to look at what you pushed on, pop it off, and send it back.
However, since there is state that we want to pass to the TLBs using the send/recv Timing/Functional/etc. APIs, which don't allow for new arguments, we need a common TLB senderState to pass between TLBs, both "forwards" and "backwards."
So, basically, the rule is that any packet received by a TLB port (cpuside OR memside) must be safely castable to a TranslationState.
