Richard Henderson 2a7567a2f3 target/microblaze: Diagnose invalid insns in delay slots
These cases result in undefined and undocumented behaviour but the
behaviour is deterministic, i.e cores will not lock-up or expose
security issues.  However, RTL will not raise exceptions either.

Therefore, log a GUEST_ERROR and treat these cases as nops, to
avoid corner cases which could put qemu into an invalid state.
