[LLVMdev] How to use MCJIT by default for a target

I think the response said that unconditionally using MCJIT everywhere was not considered viable. On the other hand, it looks like converting ARM to use MCJIT is something people will need persuading about. I'll try to find time to have a look at Andrew Kaylor's suggestion of adding a per-triple jitVariety variable to lit-cfg.

  I don't see this patch get committed. Do you want to ping it? ;)
