[PATCH] D78545: [RISCV] Make CanLowerReturn protected for downstream maintenance

[Jessica Clarke via Phabricator via llvm-commits]

jrtc27 added a comment.

I am still very confused why this is necessary. `CanLowerReturn` barely does anything other have a loop to call other functions that actually do useful work, it seems like the wrong place to hook into things. Your "explanation" is merely just "we want this because we want this". Could you please shed some light on how _exactly_ this is useful? As it stands I am none the wiser.
