turns out I should not have tried renaming FStallD to FPUStallD because that name was already used! All the same it does feel weird to have two such signals floating around \(ah pun!\)

Added some updates to divider - still not working all the time. Still a bug with signals within muldiv - specificaly MultDivE being modified during Execute stage. Seems to be triggered by ahblite signal.

Concerns:
1. I don't think the correct data buses are going to the multiplier.
2. I'm not sure the FlushF signal is correct.

Added FlushF to hazard unit.

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.
