...
Reset is missing in resettable flip-flop sensitivity list, this can lead to non-resettable FF with `rst_ni` on the data fanin of the FF.

frontend: Clean-up instruction frontend
...
The instuction frontend has become an increasingly messy part an needed
cleaning-up. The current solution contains 2 x 32 bit instruction data
fifos and 1 x 64 bit address fifo. Hence, it should be significantly
more area efficient that the previous one. The interface to `id_stage`
is a ready/valid handshake. The credit based system has been replaced in
favour of a replay mechanism as it was very brittle and overly
pessimistic.
Branch-prediction has been cleaned up: The front-end was also partially
predicting on jumps, this could have potentially let to performance bugs
if the branch detection wasn't correct in the frontend.

btb: Remove clear flag
...
In anticipation of cleaning up the branch-prediction a clear flag is no
longer needed. We know at prediction time whether the instruction is a
branch or not. This makes the effect of aliasing very unlikely.
