Reduce AXI4 queues

8ca6c10994 tilelink2: ToAXI4 can strip off low source ID bits
Some TL converters place extra meta data in the low bits of source.
Examples include the TLFragmenter and CacheCork.

This new argument makes it possible to save AXI4 ID space by reclaiming
those bits upon conversion.

a6d9884cc0 Improve integer mul/div
- Signed integer multiplication latency is now deterministic (before,
it would take an extra cycle if the multiplier was negative).
- High-part multiplication is now one cycle faster.
- RV64 MULW now takes half as many cycles as MUL.
- Positive remainders are now one cycle faster.

1f8c4ba4ca CoreplexNetwork: don't force a buffer on the coherence manager
Let the l2Config.coherenceManager create its own appropriate buffers.
This can matter if you need to make sure the buffer is in the right
place in the hierarchy for hierarchical place and route.
