With #36862 we have support for enregistering structs that are returned in multiple registers. It should be a relatively small incremental change to enable enregistering of longs that are passed or returned in 2 registers on 32-bit targets.

Marking this as future, but I'm hoping to get it into 5.0, assuming no blocking issues arise.
