5be592f870 Make checker handle not executing the same instruction as the main CPU a little better.
Also add the option for the checker to update itself with the main CPU's state if it executes an instruction differently (so it will handle DMA timing errors properly).

c23b23f4e7 Add in checker. Supports dynamically verifying the execution of instructions, as well as limited amount of control path verification. It will verify anything within the program, but anything external (traps, interrupts, XC) it assumes is redirected properly by the CPU. Similarly it assumes the results of store conditionals, uncached loads, and instructions marked as "unverifiable" are correct from the CPU.
base/traceflags.py:
build/SConstruct:
cpu/SConscript:
cpu/cpu_models.py:
    Add in Checker.
cpu/base.cc:
    Add in checker support.  Also XC status starts off as suspended.
cpu/base.hh:
    Add in checker.
