But in real hardware the PC processing runs in parallel with ALU and cannot read its results in the same cycle. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
*	Initial support for JAL.	Pavel Pisa	2019-01-31
\| \| \| \| \| \| \|	The JR, BEQ, BNE are most probably incorrect still. There is missing forwarding for pipelined execution. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>

*	Allow instruction trace from any stage	Karel Kočí	2018-01-11
\| \| \| \| \| \|	In reality this internally allows us to see stages even it we are not using pipelining but that is hidden from outside simply to not confuse user.
