O3 CPU: Add a boolean flag for instruction midway in execution
This patch adds a boolean flag to the commit stage of the O3 cpu for
tracking whether or not there is an instruction that has committed some but
not all of its microops. This is required so that the interrupts are not
handled while an instruction is midway through its execution.
