ddf4afaf71 Changes to build with a 512-bit main data bus (with all other busses 
still 64-bits).
Also, the top-level SoC_Top exposes a 64-bit bus still, so hopefully the
GFE configuration is unchanged.
This passes the isa_tests.

04ba0cb7ab Prefer tag clearing to trapping when manipulating a sealed capability 
This causes the behaviour of CCSeal and CSeal to diverge in non-trapping cases,
meaning an extra case is added to CapModify.

fb259583dc Attempt to clear tag on exception path before forwarding. 
This is likely to be bad for timing, but might just work at 25MHz.
