Re: [lto] PATCH: Add support for referencing types from function bodies

I don't think there's a perfect choice here. You reasonably want the GIMPLE to be identical on read/write, but I, also reasonably, don't want to write code we don't need in the long term.

You/I/we could instead teach the gimplifier on the LTO branch to make the transformation from CONST_DECL to its initial value. That would avoid transforming the GIMPLE as you write it.
