Add separate define HAZARD3_ASSERTIONS for enabling internal assertions,

and enable it only on the bus compliance model checks. Trying to make
the solver's life easier in instruction_fetch_match.

Add single-port bus compliance. Fix adapter not re-arbitrating following an ERROR response, causing a squashed younger load-store to remain presented to the bus.

Fix bug where an IRQ can fire during load/store dphase, followed by dphase bus exception.
...
Result was that the exception would sample the IRQ vector PC rather than the load/store instruction PC.
Fix by fencing off on in-flight dphases before asserting the IRQ. This adds a cycle of jitter
to IRQs, but is required for correct operation without adding a full exception-gathering pipeline.
