Details

Scalar replacement requires a template object. I think we also need it for inline GC allocations in JIT code.

Ideally this would use something like [1] to generate the snapshot. The whole template object system is quite adhoc/arbitrary but it might be hard to strip out of the MIR backend just yet.
