O3 CPU: Provide the squashing instruction
This patch adds a function to the ROB that will get the squashing instruction from the ROB's list of instructions. This squashing instruction is used for figuring out the macroop from which the fetch stage should fetch the microops. Further, a check has been added that if the instructions are to be fetched from the cache maintained by the fetch stage, then the data in the cache should be valid and the PC of the thread being fetched from is same as the address of the cache block.
