Fix two frontend bugs: possibility for fetch to be blocked at CIR whilst also not going to FIFO (fixed by making those signals the complement of each other) and typo in the shift value for shifting into a CIR with 32 bits of contents, which is only reachable via a CIR-locked branch to an unaligned address.

Redesign fetch queue: 2x32 + 3x16 -> 6x16.
...
Should make it easier to support finer-grained flushing,
and handle predicted branches cleanly.

RVFI monitor: blank out instructions which experienced an instruction fetch fault.
...
(previous monitor logic was ok when fetch faults weren't implemented.
If the blanked instruction has side effects, these will break other test
properties, which we would detect.)
