Implement realistic hazard resolution for JR, JALR, BEQ, BNE, BLTZ, BGEZ instructions.
The previous code worked by chance only because decode has been fully
processed including forwarding from M and W before PC processing
started. But in real hardware the PC processing runs in parallel
with ALU and cannot read its results in the same cycle.
