e894d64bca diplomacy: support := composition 
This makes it possible to treat chained composition associatively.
x := y :=? z :=* a ...

It also makes it easy to chain multiple optional adapters:
node :=? (Seq(a, b) ++ c ++ d)

c4978712c9 csr: allow for superscalar decode (#1069) 
* CSR provides a decode port to check for an illegal instruction.
   * This commit now allows for multiple instructions in decode to get this
      illegal instruction information.
   * This commit leverages the existing decodeWidth parameter. This will
      potentially over-provision the number of decode ports needed for
      RVC-enabled cores.

Closes #1068

8b58327fa4 axi4: conversion from TL does not need beatBytes (#1051) 
We used to pack the addr_lo into user bits. We don't do that anymore.
There is thus no need to waste those bits, nor to pass that arg.

21b5367259 Expand C.UNIMP correctly (#1052)
