Assign traceData to be NULL at BaseSimpleCPU constructor.

Initialize a temporary variable for thread->readPC() at setupFetchRequest() to reduce function calls.
exec tracing isn't needed for m5.fast binaries
Moved MISCREG_GL, MISCREG_CWP, and MISCREG_TLB_DATA out of switch statement and use if blocks instead.
