Korey Sewell 34715cc691 Fix offset in removeThread() function so that float registers start freeing up
from the right point (#32 usually) instead of restarting at 0 and double-freeing.

Commented out assert line in free_list.hh that will check for when double-free condition
goes bad.

Ke Meng 0b6876a0c0 The reason is that the event is supposed to put the instructions ready to execute for next cycle. And the FUCompletion event has a lower priority than CPU tick event. It is called after the iew->tick() for current cycle has already been executed and the issueToExecuteQueue has already advanced this time. And assume the issueToExecuteLatency is 1, to catch up, the increasement should be made at access(-1) instead of access(0). Otherwise I found it could increase the actual op_latency of the instructions to execute by 1 cycle and potentially put the simulated CPU into a permanent idle state.
