Removing some bottlenecks that limit that peak-IPC
- FUs depended on the result bus to know if they are going to be used on a certain cycle, this is not the case anymore, occupied bitvectors are added
- A configurable number of result buses is added (the number of buses is equal to the EX_WB pipe width)
- Modified the Fermi config file to add two ports to the operand collector
IPC with a theoretical limit of number_of_SMs*64 is achievable using this configuration
