Add deopt fuzzer tool. Can be run as a stand-alone script like run-tests. Executes first all tests of a given test suite to collect the maximum number of possible deopt points. Runs then a fuzzing phase with artificial deoptimizations triggered during testing. Works for now with mjsunit and ia32 only.
