Shreya and I found a bug with the exeuction of JAL and JALR instructions. The link was only set in the writeback stage. Once the branch predictor started correctly predicting JAL(R)s the ALU and forwarding logic need to have the PCLinkE at the execution stage in case an instruction in the next two clocks need the data.

RAS needs to be reset or preloaded. For now I just reset it.

Fixed bug with the instruction class.
Most tests now pass. Only Wally-JAL and the compressed instruction tests fail. Currently the bpred does not support compressed. This will be in the next version.

Fixed some typos with the names of signals in the branch predictor. They were causing signals to be not set. Note there is a modelsim flag which prevents it from compiling if a logic is undefined.
I will look this up and add it to the compiler.
