[llvm] r222767 - Small model and JIT generally don't go well with each other.

[Lang Hames]

Hi Joerg,

It may be worth filing a bug for this, since we still want small-code-model
to be supported in the JIT. To make this testable we'd need to add a mode
to LLI that guarantees allocations compatible with small code model.

Cheers,
Lang.
