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)

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

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.
