cpu: Move commit stats from simple to base cpu

Created stat group CommitCPUStats in BaseCPU and moved stats from the
simple cpu model.

The stats moved from SImpleCPU are numCondCtrlInsts, numFpInsts,
numIntInsts, numLoadInsts, numStoreInsts, numVecInsts.

Moved committedControl of MinorCPU to BaseCPU::CommittedCPUStats. In
MinorCPU, this stat was a 2D vector, where the first dimension is the
thread ID. In base it is now  a 1D vector that is tied to a thread ID
via the commitStats vector.

The committedControl stat vector in CommitCPUStats is updated in the
same way in all CPU models. The function updateComCtrlStats will
update committedControl and the CPU models will call this function
instead of updating committedControl directly. This function takes
a StaticInstPtr as input, which Simple, Minor, and O3 CPU models are
able to provide.

Removed stat "branches" from O3 commit stage. This stat duplicates
BaseCPU::CommittedCPUStats::committedControl::IsControl.

O3 commit stats floating, integer, loads, memRefs, vectorInstructions
are replaced by numFpInsts, numIntInsts, numLoadInsts, numMemRefs,
numVecInsts from BaseCPU::CommitCPUStats respectively. Implemented
numStoreInsts from BaseCPU::commitCPUStats for O3 commit stage.
