Add FuzzerTile
...
This tile is similar to TraceGenTile in rocket-chip, where each tile
contains a memtrace generator/fuzzer that drives the intra-tile
coalescer and the rest of the memory subsystem.

Split IO for lookup and dealloc in InflightTable
...
The usage of `lookup` and `lookupSourceId` ports were being conflated in
terms of table lookup and dealloc. Now `lookupSourceId` solely controls
lookup operation and vice versa. This simplifies pipeline reg logic in
uncoalescer.

Fix uncoalesced response being dropped
...
Need to use fire instead of valid so that the uncoalescing /
inflighttable freeing logic happens exactly once at the fire time.
FIXME: might result in long ready chain that goes from TL-D port all the
way to the response queues.

Streamline upstream flow with regards to CoalSourceGen
...
CoalescerSourceGen was prematurely reclaiming sourceIds in the presence
of coalResp backpressure, since it was not referring to coalResp.fire
and instead setting ready to always-true. With this change
CoalSourceGen properly propagates both downstream and upstream
backpressure.
