The testing of JIT and MCJIT is already a bit of a mess, and changing the default to MCJIT for some platforms while leaving it as JIT for other platforms would make things considerably worse.  I think at this point we'd need to consider cleaning up the JIT/MCJIT nightly tests as a pre-requisite to changing the default, regardless of other considerations.

  I agree that we should clean up JIT/MCJIT tests, then change to MCJIT
until it pass those tests.
