cpu: Move execute stats from simple and minor to base
Created stat group ExecuteCPUStats in BaseCPU and moved stats from the
simple and minor cpu models.
The stats moved from SimpleCPU are dcacheStallCycles,
icacheStallCycles, numCCRegReads, numCCRegWrites, numFpAluAccesses,
numFpRegReads, numFpRegWrites, numIntAluAccesses, numIntRegReads,
numIntRegWrites, numMemRefs, numMiscRegReads, numMiscRegWrites,
numVecAluAccesses, numVecPredRegReads, numVecPredRegWrites,
numVecRegReads, numVecRegWrites.
The stat moved from MinorCPU is numDiscardedOps.
Also, ccRegfileReads, ccRegfileWrites, fpRegfileReads, fpRegfileWrites,
intRegfileReads, intRegfileWrites, miscRegfileReads, miscRegfileWrites,
vecPredRegfileReads, vecPredRegfileWrites, vecRegfileReads,
and vecRegfileWrites are removed from cpu.hh and cpu.cc in O3CPU. The
corresponding stats in BaseCPU::ExecuteCPUStats are used instead.
Changed the getReg, getWritableReg, and setReg functions in the O3 CPU
object to take the thread ID as a parameter. This is because the stats
in base are stored in vectors that are indexed by thread ID.
