On top of #36970 this has a 0.01% reduction in system image code size. Mostly due to removal of a few GC frame slot and write barriers.
I've also tested a few different other options including teaching the llvm passes about the boxing functions and allocating the boxes as global array directly and this approach seems to be the best balance between code size and speed.
