This revision is now accepted and ready to land.

I'm obviously a big fan of the codegen improvements resulting from this patch...but it always feels unpleasant to add a target-specific workaround for what seems to be a bug/limitation elsewhere. I think it does make sense to land this workaround as it's not clear how feasible improving the coalescer would be, but perhaps you could file an issue to track this problem?
