Some 68060 tests: · jsonn/src@34a3b6c

Commit

Some 68060 tests:

- 060sp is calling glue to Motorolas test code for the 68060SP. We dont call
  the ftest #3, as it requires special kernel support not wanted normally.
- emuspeed is a partially table-driven instruction, thus easily extensible
  benchmark. Tests are in for the emulated-on-68060 mul 32->64bit and
  div 64->32bit.
