So we can never again change the default CPU on any target because 
some user of the C API may be relying on it? That *is* insane, and I 
strongly oppose a move in that direction. 
No, I'm saying that the default CPU in the JIT should always be the CPU we're actually running on.  That's not insane, that's how any sensible JIT would work.

As I understand it, you're still getting the code you ask for, just a 
less efficient version of it.
