ee1a9485df Enforce physical-address canonicalization 
When xLen > paddrBits, enforce that physical addresses are zero-extended.
This works by checking that the _virtual_ address is _sign_-extended, then
checking that its sign is positive.

7c9a1b0265 Correctly check for virtual-address canonicalization 
The previous check was necessary but not sufficient.

ddaeedf2d0 coreplex: make HasTiles more generic 
HasTiles now deals with only extremely general tile IOs.
Some RocketTiles specific behavior moved into RocketCoreplex.
BaseTile now has optional LocalInterruptNode.

a1ebe6da4d Prevent frontend deadlock fetching from uncacheable memory 
After detecting a corrupted BTB, don't speculatively update it until
the next non-speculative fetch.  This prevents the frontend from replaying
forever.

diplomacy: remove the :=? operator in favour of magic :*=* (#1139) 
The reason for the :=? operator was for when you have an adapter chain
whose direction of cardinality you could not know. We used explicit
directives to tell these compositions which way to go.

Unfortunately, that makes the API leaky. You think the chain of adapters
is just one adapter, but you have to use strange Cardinality scopes to
use it. That's just bad.

The new :*=* just automagically figures it out from the graph.

e489c4226e diplomacy: remove node arity and allow empty Nexus nodes (Xbars) 
This removes the mostly obsolete 'numIn/Out' range restrictions on nodes.
It also makes it possible to connect optional crossbars that disappear.

val x = TLXbar()
x := master
slave := x

val y = TLXbar()
x :=* y // only connect y if it gets used

This will create crossbar x, but crossbar y will disappear.
