Philip, I've published alternative patch https://reviews.llvm.org/D97554 wit your idea to show the impact.
>From my point of view it looks better in terms that we explicitly process deopt gc pointers as other gc values.
The disadvantages is that now we will have a lot of dead tied-def registers and deopt value will be listed twice in uses.

So generally the approach you proposed is a bit cleaner in understanding but costs a bot more in terms of compile time.
