Eliminated extra register and fixed ports to icache.
...
Still need to support physical tag check and write in icache memory.
Still need to reduce to 1 port SRAM in icache.
I would like to refactor the icache code.

Partially working icache.
...
The current issue is a StallF is required to halt the icache from getting an updated PCF. However
if the dmemory is the reason for a stall it is possible for the icache stall to hold the d memory request continuously causing d memory to repeatedly read from memory. This keeps StallF high and
the icache FSM is never allowed to complete.
